ABSTRACT:
A logic circuit including a pair of FETs connected in parallel and including first and second common current terminals, each of the FETs further having a control terminal connected to receive a logic signal thereon. A negative differential resistance device affixed to one of the first and second common current terminals and having a conductance characteristic such that the device operates at a peak current when one of the FETs is turned ON and at a valley current when both of the FETs are simultaneously turned ON. A load resistance coupled to the other of the first and second common current terminals and providing an output for the logic circuit.
