ABSTRACT:
A bias current compensator to supply the input bias current of a transistor. The bias current compensator may be used, for example, with the controlled amplifiers used in an automatic gain control system. The bias current compensator prevents bias current changes, caused by a varying control signal, from appearing in the output of the controlled amplifier. The bias current compensator includes a current source, first, second, and third transistors, and a feedback amplifier.
