ABSTRACT:
A current source circuit includes a current mirror circuit having a master transistor and at least one slave transistor. The master transistor is coupled to a differential amplifier. The differential amplifier includes a pair of transistors, one thereof being coupled to a reference current source and the master transistor and the other one having a collector electrode connected to the base electrodes of the master and slave transistors for producing a current through the collector electrode substantially equal to the total current flow through the base electrodes of the master and slave transistors.
