ABSTRACT:
A monolithic bipolar current mirror circuit having linear mirror-gain over four orders of current magnitude independent of device-beta (even if .beta..fwdarw.1). A third bipolar feedback transistor coupled to a unipolar buffer transistor provides voltage feedback to eliminate input loading and thereby eliminate the dependence of mirror-gain on device current-gain. The bipolar current mirror circuit can be frequency compensated and can be implemented using either PNP or NPN devices in BiCmos integrated circuit technology.
