Abstract

When a switch is set to off, and a switch is set to on, the voltage of a SigOut terminal is stabilized with a reference voltage, and a bias voltage is applied to a capacitor. Changing the switch from on to off, with the bias voltage retained in the capacitor, a detection signal which is input via a SigIn terminal is amplified with the reference voltage as a reference, and an amplified signal is output from the SigOut terminal.
