Differential amplifier and analog/digital converter |
摘要 |
Disclosed herein is a differential amplifier including: an input terminal configured to receive an input signal; an output terminal configured to output an output signal obtained as a result of amplifying the input signal; an amplification part configured to amplify the input signal to generate the output signal; a load circuit which is connected between the amplification part and a power-supply terminal, and is provided with a first-conduction transistor, and a changeover switch configured to switch a connection between a gate electrode of the first-conduction transistor and a drain electrode of the first-conduction transistor to a connection between the gate electrode and the output terminal or vice versa; and a leak cancel switch configured to generate a leak cancel current for reducing an off leak current flowing through the changeover switch.
