Abstract
An amplification circuit includes an amplifier, a first capacitor including a first terminal connected to an input terminal of the amplifier, a second capacitor including a first terminal connected to the input terminal of the amplifier and a second terminal connected to an output terminal of the amplifier, and a correction unit configured to correct a difference in bias dependency between capacitance values of the first and second capacitors.
