Abstract
A current switch circuit including a current switch including a first transistor and a second transistor connected as a differential pair and receiving a differential logic signal at their bases, and logic signal controlling circuitry coupled to the first and second transistors for offsetting a transition starting point of to differential logic signal to offset a self-heating induced shift in a switching threshold of the current switch.
