摘要：A variable resistance gain control integrated circuit has a resistor insertedbetween the emitters of two transistors serving as a differential pair, and two transistorswhich serve as an active load and have their emitters connected to the emitters of thetwo transistors serving as a differential pair. The resistor and the transistors serving asthe active load are formed within a single semiconductor island region.
