ABSTRACT:
A high-speed logic circuit including a logic part formed of a differential transistor circuit and a feedback part for feeding the in-phase output of the differential transistor circuit back to the out-of-phase input terminal of the differential transistor circuit is disclosed in which a constant current source circuit is provided in the feedback part to keep constant a current flowing through the feedback part.
