The time sequence controller meets the requirement of changing time sequence power supply time delay through capacitors connected from C1 to C4, and the time delay is set to be TDelay＝CDelay×0.1，TDelayIn units of seconds, CDelayThe unit of (2) is uF. The source of P-type FET Q1 is connected to the input of positive voltage, and is connected to the gate through voltage dividing resistors R6 and R7, and by controlling the | V of FET Q1GS| and | VGS(th)The magnitude relation of the | and the turn-on voltage determines whether the P-type field effect transistor Q1 is conducted, thereby determining whether the drain has positive voltage output.
The enable terminal IN of the Switch1 is connected to the output OUT1 of the timing controller, and the Switch is controlled to be turned on or off by the timing controller OUT1, so that the P-type control fet Q1 is turned on or off. The S end of the Switch1 is connected with a resistor R7, and the D end is connected with two resistors R9 and R10 in series to the ground; when the Switch1 enables the IN terminal to input high level, the Switch1 is turned on, and a voltage difference | V appears between the gate and the source of the FET Q1GSBy adjusting the resistances of the resistors R6, R7, R9 and R10, | VGS│>│VGS(th)And if the voltage is turned on, the field effect transistor Q1 is conducted, and the drain electrode outputs a positive voltage which can supply power to the drain electrode of the GaN power amplifier tube. When OUT1 of the timing controller is not output, it is grounded, and the Switch1 enables IN to be at low level, | VGSAnd 0, the effect tube Q1 is not conducted, and no output voltage exists at the drain electrode. Meanwhile, when the Switch1 is turned on, the pin VIN1 of the feedback timing controller has positive feedback voltage input, so that the output OUT1 of the timing controller can work normally; when the Switch1 is open, the pin VIN1 has no feedback input.
The S terminal of the Switch2 is connected to the negative voltage supply through two resistors R11 and R12, the D terminal is directly connected to ground, and the enable terminal IN is connected to the output OUT2 of the timing controller; the negative voltage Vgg is output between the series resistors R11 and R12, when no output is generated at the pin OUT2 of the timing controller, the enable end IN of the Switch2 is at a low level, the Switch is turned off, and at the moment, the Vgg outputs-8V to supply power to the grid electrode of the GaN power amplification tube; when the enable end IN of the Switch2 inputs high level, the Switch is turned on, the voltage is divided by the resistors R11 and R12, and Vgg outputs-3V, thereby achieving the purpose of negative voltage conversion.

When the UP/DOWN pin rises, OUT1 outputs high level, and the voltage output by OUT1 enables the input of a feedback pin Vin 1; after the DELAY2, the OUT2 outputs high level, and the voltage output by the OUT2 enables the Vin2 to be input; after the DELAY3, the OUT3 outputs high level, and the voltage output by the OUT3 enables the Vin3 to be input; after the DELAY4, the OUT4 outputs high level, and the voltage output by the OUT4 enables the Vin4 to be input; the feedback voltage input from the pins Vin1 to Vin4 ensures that VOUT1 to VOUT4 are normally output in time sequence.
As shown in fig. 3, taking the present apparatus as an example of supplying power to a GaN power amplifier tube, the GaN power amplifier tube should be powered on by first supplying a negative gate voltage and then supplying a positive drain voltage. When the system is powered on, firstly, the voltage with Vgg of-8V is output to supply power to the grid electrode of the power amplification tube. When the Switch4 is connected to +5V voltage, the UP/DOWN pin rises, the OUT port outputs high level, the Switch1 is turned on, and the resistances of the resistors R6, R7, R9 and R10 are adjusted to make VGS│>│VGS(th)Q1 is conducted, VOUT outputs +28V voltage, and the drain of the power amplifier tube is supplied with positive electricity. The voltage output by the OUT1 enables Vin1 to feed back and input (the Vin1 refers to the voltage of 0.6V), the OUT2 outputs high level after the DELAY of DELAY2, the Switch2 and the Switch3 are conducted, and the voltage dividing resistor is adjustedThe resistance values of R11 and R12 output Vgg which is-3V, and meanwhile the voltage output by OUT2 enables Vin2 to feed back and input, so that the normal work of the output port of OUT2 is ensured. After the DELAY3, the OUT3 outputs high level, and the voltage output by the OUT3 enables the Vin3 to be input; after the DELAY4, the OUT4 outputs high level, and the voltage output by the OUT4 enables the Vin4 to be input; the feedback voltage input from the pins Vin1 to Vin4 ensures that VOUT1 to VOUT4 are normally output in time sequence.
When the GaN power amplifier tube is powered off, the positive voltage of the drain electrode is cut off first, and then the negative voltage of the grid electrode is cut off. When the Switch4 is connected to ground, the UP/DOWN pin has a falling edge, the OUT4 outputs a low level, and the feedback input of Vin4 is 0; after the DELAY4, the OUT3 outputs low level, and the feedback input of Vin3 is 0; after the DELAY3, the OUT2 outputs low level, the Switch2 and the Switch3 are disconnected, Vgg is changed from-3V to-8V, power is supplied to the grid electrode of the power amplification tube, and the feedback input of the Vin2 is 0; after DELAY2, OUT1 outputs low, where Vin1 feedback input is 0 and Switch1 is turned off, and where V isGS│<│VGS(th)Q1 is not conducted, VOUT output is reduced from +28V to 0V, and the power-off process of the power amplifier tube is completed.
In summary, the invention can perform time-series power supply to devices such as a nitride grafting (GaN) power amplifier and the like which need to perform time-series power supply, thereby ensuring the normal operation of the devices which need to perform time-series power supply.
