摘要：A differential circuit including: a first MOS transistor and a second MOS

transistor that constitute a differential pair; a determination unit to determine a level of adetermination target signal that is based on at least one of differential inputs being inputto gate of the first MOS transistor and a gate of the second MOS transistor; and a

voltage changing unit to change a back gate voltage that is supplied to both back gatesof the first MOS transistor and the second MOS transistor according to a determinationresult of the determination unit, and an OP-amp will be provided.
