Abstract
PURPOSE: To integrate a detecting resistance by using a shunt transistor formed with characteristics matched on the same substrate through having a base and an emitter connected in common in a current limiting circuit using base-emitter voltage of the transistor as a reference voltage.
CONSTITUTION: A base and an emitter of output transistor Q1 and shunt transistor Q3 are connected in common, and an input current Ii is supplied between the base and the emitter from a signal source S. The collector of the shunt transistor Q3 is connected to a power source Vs by way of a detecting resistance Rs and also connected to the base of a control transistor Q2. The collector current of the control transistor Q2 controls said input current Ii for dimension.
