Patent ID: 8264277

Claim:
A differential amplifier circuit, comprising: a first input stage comprising a pair of PMOS transistors and a first current source, for causing an output current to flow based on two input voltages; a second input stage comprising a pair of NMOS transistors and a second current source, for causing an output current to flow based on the two input voltages; a folded cascode amplifying stage, into which the output current of the first input stage flows and from which the output current of the second input stage is drawn, thereby outputting a voltage; an output stage for outputting an output voltage based on the voltage of the folded cascode amplifying stage; a first correction current generation circuit for causing a first correction current to flow into the output stage based on a supply current of the first current source; and a second correction current generation circuit for drawing a second correction current from the output stage based on a supply current of the second current source.
