ABSTRACT:
A differential amplifier includes differentially connected transistors, a first current mirror circuit used as an active load of the differentially connected transistors, and a second current mirror circuit connected to the common emitter side of the differentially connected transistors so as to reduce an off-set DC current that may be produced at the output terminal of the differentially connected transistors.
