Abstract
The present invention includes circuitry wherein a pair of voltage supply terminals are included, with a first current source connected to one voltage supply terminal and a second current source connected to the other voltage supply terminal. A load connects the first and second currect sources. A field effect transistor has a first current handling terminal connected between the first current source and load, a second current handling terminal connected to the other voltage supply terminal, and a current control terminal connected between the load and the second current source. The second current source is of the type wherein the current thereacross is substantially independent of changes in voltage thereacross.
