Circuit for integrated current mirror has constant current branch with two diode functions whose source connection potential determines cascade transistor control electrode fixed potential

摘要

The circuit has cascade stages (T1,T2;T3;T4) for input and output current. The cascade stage carrying the input current has a cascade transistor (T1) whose control electrode is supplied with a fixed potential (C) derived from a constant current branch with a series circuit of two diode functions (T5,T6) whose connection on the current source side carries a potential (K) determining the fixed potential for the cascade transistor's control electrode.
