ABSTRACT:
The chopper type differential amplifier according to this invention includes a differential amplifier having a first input end and a second input end, a first input terminal supplied with a first input signal, a second input terminal supplied with a second input signal, a first MOS gate capacitor having its gate electrode connected to the first input end of the differential amplifier and its lower electrode connected to the first input terminal, a second MOS gate capacitor having its gate electrode connected to the second input end of the differential amplifier and its lower electrode connected to the second input terminal, and a precharging circuit which supplies a precharging voltage to the gate electrode of the first MOS gate capacitor and the gate electrode of the second MOS gate capacitor during the precharging period, wherein the precharging voltage is a voltage which is all the time higher than the voltages of the first input signal and the second input signal.
