Abstract
According to one embodiment, a chopper stabilized amplifier includes an input unit, a first chopper, a first amplifier, and a switch circuit. The input unit receives a differential input signal at a first input terminal and a second input terminal. The first chopper modulates the differential input signal based on a first control signal and an inverse signal of the first control signal. The first amplifier amplifies the signals with the modulated differential output from the first chopper. The switch circuit is provided between the input unit and the first chopper, and receives a second control signal and reduces input currents which flow in the first chopper when the first chopper performs a modulating operation, by using an operation with the second control signal.
