摘要： An amplifier circuit having a differential amplifier, provided in a semiconductor integrated circuit is disclosed. The differential amplifier has one input connected to a reference voltage generating circuit. The voltage outputted from the reference voltage generating circuit includes a voltage fluctuation depending on the fluctuation in power-supply voltage Vcc. However, a fluctuation absorbing circuit comprising resistors 51 and 52, diodes 53 and 54, and a capacitor 55 absorbs the voltage fluctuation thereof. As a result, the change in offset voltage of the differential amplifier is prevented, resulting in an improvement of a power-supply rejection ratio.
