Abstract:
An amplifier circuit includes an amplifier unit that amplifies a signal received by an input terminal and outputs the amplified signal to an output terminal, a feedback capacitor that is connected between the input terminal of the amplifier and the output terminal, and a controller that varies a capacitance in the feedback capacitor for a certain period when a potential of the output terminal in the amplifier unit becomes higher or lower than a certain potential.
