ABSTRACT:
A SPL (or Super Push-pull Logic) circuit is provided which includes: a first variable resistor circuit connected between the collector of an input transistor and a first supply voltage terminal (GND) a second variable resistor circuit connected between the emitter of the input transistor and a second supply voltage terminal (V.sub.EE) and a push-pull output circuit. The second variable resistor circuit includes an N-channel MOSFET which has its gate electrode made receptive of any of the output signals of the SPL circuit, a differentiated signal of the output signal, and an inverted signal of the input signal.
