Abstract
A voltage follower circuit comprises an input terminal; an output terminal; first and second power supply terminals; a first transistor of one conductivity type having a base connected to the input terminal; a second transistor, opposite in conductivity type to the first transistor, having a base connected to the collector of the first transistor, a collector connected to the output terminal and an emitter connected to the first power supply terminal; a third transistor having a base and collector connected to the output terminal and an emitter connected to the emitter of the first transistor; a fourth transistor of the one conductivity type having an emitter connected to the second power supply terminal; and a fifth transistor of the one conductivity type having an emitter and base respectively connected to the emitter and base of the fourth transistor and a collector connected to the base of the fourth transistor and to the first power supply terminal through a resistor.
