The PSRR (power supply rejection ratio) of a current mirror circuit is increased by cascoding the output transistor of the current mirror, and the precision of the circuit is enhanced by employing a frequency compensated gain stage utilizing a field effect transistor to drive a bipolar current output transistor.

Abstract

The PSRR (power supply rejection ratio) of a current mirror circuit is increased by cascoding the output transistor of the current mirror, and the precision of the circuit is enhanced by employing a frequency compensated gain stage utilizing a field effect transistor to drive a bipolar current output transistor.
