摘要

An offset cancellation amplifier where during a first period of a data output period, an output voltage and a reference voltage are supplied to the gates of a first differential pair, and the output voltage is accumulated in first and second capacitors while an input voltage is supplied in common to the gates of a second differential pair. During a second period, the output voltage is accumulated in the first capacitor, while the reference voltage is accumulated in the second capacitor. During a third period, the gates of the first differential pair cease to be supplied with the output voltage and with the reference voltage, respectively, and are supplied with the voltages accumulated in the first and second capacitors, respectively. The gates of the second differential pair are supplied with the output voltage and with the input voltage, respectively.
