摘要
A signal amplification circuit includes an input terminal; a first chopper modulation circuit; a first amplifier having an amplification circuit and a chopper demodulation circuit, a capacitance feedback circuit having a second chopper modulation circuit, a first switch constituting a voltage follower circuit with the amplification circuit; a second switch; a second amplifier to convert the differential output signal from the second output terminal into a single-end signal; and a filter to pass at least a predetermined frequency component of the chopping frequency from the single-end signal from the second amplifier to output an output signal of the signal amplification circuit.
