Abstract
PURPOSE: To control collector current of one transistor to any selected value by a base and an emitter and formed with characteristics matched on the same substrate through common connection and the ratio of emitter area is changed according to a desired shunt ratio in a shunt circuit using integrated transistors.
CONSTITUTION: A base and an emitter of transistors Q1, Q2 are connected in common to integration and formed with characteristics mtched on the same substrate. Then these transistors are arranged to have the emitter area ratio changed according to a desired shunt ratio. An input current is supplied to the base from a signal source S to obtain a collector current in the desired shunt ratio. In the drawing, Vs represents a power source.
