The output signals of the macrocells 206 will be provided to the tri-state output punches 208, M and also to the feedback circuit of the switch matrix circuit 106. Each tri-state round-out buffer 208 can be enabled by M, and used as a round-out punch, or by adding K disable to enable the I / O port 111 to provide the input signal to the PLD. The enabling or disabling signals required by the tri-state output punch 208 are provided by the AND array and the logic distributor circuit 204. When the three-state output buffers 208 are enabled, the output signal of the three-state output buffer 208 will not only pass through the I / O ports 111, but also go through the feedback lines to the exchange At matrix circuit 106. When the tri-state wheel output punch 208 is disabled, the input signals from external circuits will be provided to the switch matrix circuit 106 through the I / O port 111. The switch matrix circuit 106 includes circuits that can distribute the signals received from the tri-state output buffers 208 and I / O ports 111 back to the programmable array embedded blocks (PAL) 101-104. FIG. 3 is a cross-sectional view showing the part where the switch matrix circuit 106 and the input terminal of the input puncher 202 are connected. As shown, the switch matrix circuit 106 includes a number of circuit logic gates 304 that are all fed to the input terminals of an input buffer 202. In the switch matrix circuit 106, only the path logic gate 304 can be enabled, and a signal similar to Vs is provided to the input terminal of the wheel buffer 202, and M becomes the signal Vi. As shown in the circuit of FIG. 4 which is equivalent to the electronic circuit of FIG. 3, the majority of the channel editing gates 304 for the input weighing scale 203 are supplied with Μ, which will be. {Binding Λ (please read the note on the back first Please fill in this page for details) The paper standard of the Ministry of Economic Affairs Central Bureau of Standards and Staff's Consumer Cooperative Printed Paper is applicable to the Chinese National Standard (CNS) Α4 specification (210Χ297mm) 4 9 1225 Printed by the Ministry of Economic Affairs Central Standards Bureau's Staff and Consumer Cooperative A7 B7 5. DESCRIPTION OF THE INVENTION (5) A capacitance value C is created, and the line resistance will cause a resistance value R at the input end of the input buffer 202. Therefore, between these signals Vs and Vi, an RC delay value will be added.

Description of the invention (8) I Μ 白 Vs decides Vo. First of all, using the mathematics Μ Vi to represent Vs 0. From the equivalent circuit diagram of Figure 1 1 1 1 4 we can see that VS can be used by Μ Vi The following equation plus M decides 1 1; /-V 1 I please 1 I (1) 1 = (Vs -V i) / R first read 1 I 1 1 (2) 1 = C (dV i / dt) Solve equations (1) and (2) on the back 1 1 of 1 and use V i to represent V st to obtain the following formula 1 event 1 program · item and then 1 fill (3) V s = V ί + RC (dV i / dt) Page 1 of this policy for further understanding how V i can determine Vs f 5th ΓΒΙ m To represent the timing of the voltages V s, V i, and V o in Figure «> _✓ 1 4 when a specific V s signal 5 0 0 is received 1 1 Figure 1 In Figure 5, the Vs signal 5 0 0 contains two pulses > a slow pulse with a flat slope of 1 1-a pulse 502 with a flat slope, and a second pulse with a steep slope with rapid exchange 1 pulse 504 > the signal 5 from the picture 5 1 0 It can be seen that if the signal VS is like 1 | in the pulse wave 502-like a slow exchange with a flat slope, d V i / dt will have a smaller value of 1 I, and M will exist in equation (3) A small amount or absence of the RC delay 1 delay component »This makes V i as shown in pulse wave 512 approximately equal to VS 〇 However $ 1 when the signal Vs as in pulse wave 5 04 is rapidly exchanged with a steep slope 1 1 < d V i / dt will have a larger value, so that in equation (3) there will be 1 1 RC delay component as shown in pulse wave 5 1 4 <) 1 1 The output of the pulse generator is usually transferred by the input pulse wave-special Set 1 I voltage > For example, the transfer operation at 1.5 V. To compensate for any RC delay component of the switch matrix 1. Generally, the transfer operation of Vo is expected to occur at 1 1 Vs instead of V i transfer. At the moment when 1.5V passes 3, the desired 1 V c signal 5 20 is shown in Figure 5, and its transfer action is shown as a dashed line »It is caused by the Vs signal 1 1 This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X 297mm) 8 9 1225 A7 300355 __B7 V. Description of the invention (9) The moment 500 transfers through 1.5V. In order for the input punch to provide the V signal 520 at its output, it is generally desired that the round buffer has a variable input threshold voltage. For the transfer of the high logic level of the Vs pulse waves 512 or 514 to the low logic level, the threshold voltage is shown at the intersection of the broken lines with the pulse waves 512 or 514. The point above the pulse wave should be higher than 1.5V. Secondly, as shown by the intersection of the dotted lines with the Vi pulses 512 or 514, M and equation (3) show that when the slope of the Vs pulse is steeper, the critical voltage should be further away from the Vi 1.5V point above the pulse wave. Figure 6 shows an electronic circuit of one preferred embodiment of the input buffer of the present invention, which can use a variable input threshold voltage from a Vi signal similar to 500 from the switch matrix circuit at a high logical level to low The movement of the editing level generates a Vo signal similar to the 520th plaque No.520. The turn-in punch of FIG. 6 includes a first inverter 60 2 that has a turn-in terminal forming the input (IN) of the scale, and a wheel coupled to the output (OOT) of the buffer Output terminal. The input source also includes a PMOS pull-up transistor 604, which has a gate connected to the input terminal of the inverter 60 2 and a source connected to Vdd. The NMOS switching transistor 606 has a drain connected to the drain of the transistor 604, and a source connected to the output of the inverter 602. The diagonal line above the gate of the transistor 606 indicates that the channel has an excess ion implantation amount so as to provide a depleted transistor with a negative critical voltage. The depletion transistor 606 prevents the NMOS critical voltage drop from its source to the drain. In addition, it is worth noting in Figure 6M and subsequent figures that a PMOS transistor similar to 604 is shown in the circle of its gate M, and is similar to 606 -------- {装-(Please Read the precautions on the back and then fill out this page.) The paper standard printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs is compliant with the Chinese National Standard (CNS) Α4 specifications (210 × 297 mm) 9 9 1225 Employee Consumer Cooperative of the Central Bureau of Standards The size of the printed paper is in accordance with Chinese National Standard (CNS) A4 specifications (210Χ 297 mm) 91225 A7 B7 5. Invention description (10) The NMOS transistors do not have circles on their gates. The 6-in round-in slow balance additionally includes a stack of turn-on delay transistors 608. The stacked transistor 608 has a source connected to the input terminal of the inverter 602, and a drain connected to the node nl of the gate of the transistor 606. The gate of the stacked transistor 608 is connected to a reference voltage INREF. This INREF is preferably set to Vdd. The diagonal line on the gate of the transistor 608 is similar to that of the transistor 606, indicating that the channel has an extra implanted amount of chicks so that a depleted transistor can be produced. It is worth noting that a transistor of the stacked transistor system is defined by a fixed gate voltage, rather than using a change in the voltage applied to its source under a changing gate voltage, and adding K Turn on and off. In a stacked transistor, when (Vg-Vs)> Vt, where Vg is the gate voltage, Vs is the source voltage, and Vt is the critical voltage of the transistor, the stacked transistor will Will open. When (Vg-Vs) < Vt, the II transistor will be cut off. The inverter 602 provides a nominal critical wiper, for example 1.5V. In order to change its input threshold voltage from the threshold voltage of the inverter 602, M can provide a larger threshold voltage during the transfer operation from a high winding unit level to a low logic level, in which a transistor 604 is provided. If the transistor 604 is not included and the M inverter 602 operates, its threshold voltage will be determined by the ratio of its PMOS pull-up transistor channel width to its NMOS pull-down transistor channel width. If the transistor 604 is combined with the pull-up transistor on the inverter 602, the width of the transistor 604 can be added to the pull-up transistor on the inverter 602, M determines the transistor ratio, so it can be increased The threshold voltage of the input end of the input buffer. 10 {Cloth ------ order ------ {(please read the precautions on the back before filling out this page) The paper standard printed by the Staff Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 9 1225 A7 _ B7 V. Description of the invention (11) The minimum value provided by the inverter 602 alone, and the maximum value obtained by working together with the inverter 602 and the transistor 604 At this time, the change of the threshold voltage can be controlled, so the electric crystal hips 606 and 608 are provided. A resistance value can be generated through the transistor 608, and a parasitic capacitance value can be generated at the gate of the transistor 606, so that M forms an RC delay value. During the movement of the signal input to the buffer from the high logic level to the low logic level, the capacitance at the gate of the transistor 606 will slowly discharge, and the transistor 606 will slow down. Break. In the case where the transistor 606 is slowly turned off, the current from the transistor 604 will gradually decrease, and at the wheel-in end of the buffer, a varying threshold voltage is created. In order to make the threshold voltage of the input buffer change to compensate for the RC delay value generated by an exchange matrix circuit, the channel widths of the transistors 606 and 608 have to be specially controlled during manufacturing. The channel widths of the transistors 606 and 608 are set so that the parasitic capacitance value at the gate of the transistor 606 and a resistance value generated by the transistor 608 can provide an RC delay value so that It can compensate the RC delay value of the switch matrix circuit to which the input source is connected. In the operation of the circuit in Figure 6, first, assume that IN is at a high logic level. When MIN is at the high logic level, the PMOS transistor 604 will be turned off. In addition, when IN is at a high winding level, the source of the stacked transistor 608 will be above the reference voltage IHREF, and the transistor is turned off. In the case where IHREF is Vdd and the transistor 608 is a depleted transistor, the node nl will be a high buried level, or Vdd, and the M node nl is a high logic level, the transistor 606 will be activated.

V. Description of invention (13), the critical voltage at the input end of the buffer will not transfer similarly. When any rate of IN Μ goes to the high logic level, the PMOS transistor 604 will quickly break off, and there is no capacitance at the source of the transistor 606 that can change the operation rate of the electric crystal 604 . In order to make the buffer of the present invention compatible with TTL, the inverter threshold voltage of the inverter 602 can be set to about 1.5V. Because it is used in a CMOS balancer similar to inverter 6 02, there is usually a difference of 0V to 5V between Vss and Vdd.
