Abstract
PURPOSE: To ensure the sampling featuring a small attenuation factor and a high accuracy by using two differential amplifiers featuring the single output active load and giving charge/discharge to the holding capacity via the negative feed back to be given to the high-gain amplifier.
CONSTITUTION: The 1st differential amplifiers 43 and 44 featuring the single output active load each are inserted to the output generation points of 2nd differential amplifiers 45 and 62 respectively. The output generation points of amplifiers 43 and 44 possess capacity element 63 for signal holding and are also connected in negative feedback to the 1st differential amplification part via high-input impedance element 46. Then the analog signals are applied to the input teminals of amplifiers 43 and 44, and the signals held by capacity 63 are delivered via element 46.
