ABSTRACT:
A differential amplifier circuit wherein one collector of the multicollector of each of first, second and third inverse NPN transistors is connected to a base of the corresponding transistor; the first and second transistors are used as differential input transistors; the other collector of each of the first and second transistors is connected to a PNP transistor serving as a load current source; and an output is derived through the third transistor connected to the second transistor.
