ABSTRACT:
A negative-phase output signal in an ECL circuit is extracted by an emitter-follower circuit, and the extracted signal is differentiated at its leading edge by a capacitor driven by the emitter-follower circuit so as to form a pulse wave, thus the differentiated signal drives a transistor connected in parallel with an emitter-follower resistor to which a positive-phase output signal is supplied. With this operation, a large amount of current flows only at the trailing edge of the output signal to shorten the fall time of the output from the logic circuit.
