ABSTRACT:
A metal oxide semiconductor field effect transistor (MOSFET) current mirror circuit with a cascode output in which maximum operating ranges are achieved for the power supply voltage and cascode output biasing voltage. Replica biasing ensures adequate biasing for the cascode driver transistors and accurate current mirroring.
