Abstract
In a transistor differential amplifier circuit wherein first and second lateral transistors are connected as loads between respective collectors of a pair of differential amplification transistors and a first power supply terminal, a common emitter of the amplifying transistors is connected to a second power supply terminal through common impedance means, the first lateral transistor is made a multicollector structure, and an output is derived from only one collector of the first lateral transistor, the improvement comprising the fact that the second lateral transistor is also made a multicollector structure and that a collector of the second lateral transistor as corresponds to the aforecited output collector of the first lateral transistor is connected to the second power supply terminal.
