ABSTRACT:
A switched-capacitor amplifier circuit produces accurate output signal even if the input signal varies rapidly at every sampling phase. Two capacitors having the same capacitance are connected, in series with the input of an operational amplifier circuit. A switching circuit is connected between a first terminal and ground terminal. The two capacitors are connected with the first terminal.
