ABSTRACT:
Herein disclosed is a logic circuit which has an input bipolar transistor for receiving an input signal at its base; variable impedance circuit having at least a first P-channel MOSFET connected between a first supply voltage and the collector of the input bipolar transistor; a second N-channel MOSFET connected between the emitter of the input bipolar transistor and a second supply voltage; an output bipolar transistor connected between the first supply voltage and the output terminal of the circuit for receiving the collector potential of the input bipolar transistor at its base; and a third, pull-down MOSFET connected between the output terminal and the second or third supply voltage.
