ABSTRACT:
A junction FET switching circuit and method in which the gate-source voltage of the switching FET is varied with changing temperature so as to maintain the FET channel resistance substantially constant over a selected temperature range. An offset is introduced to the gate-source voltage to permit adequate voltage variation over the temperature range.
