とを特徴とする増幅器。 A voltage signal is converted to a current signal in an amplifier configured with a differential amplifier that amplifies the first input signal input to the non-inverting input terminal in positive phase, outputs the positive phase amplified signal, and inputs the signal to the inverting input terminal after negative feedback. An amplifier characterized in that a current source supplying the second input signal is connected to the inverting input terminal of the differential amplifier via an on/off switch.
