Abstract
A first field-effect transistorized constant current supply provides a first relatively constant output current. A second field-effect transistorized constant current supply is cascaded with, and driven by, the first current to provide a more highly regulated second constant output current. The system is self-starting and latch free. The second output current may be employed to drive a current mirror with a plurality of output current paths.
