Differential switching circuit.

摘要

A differential switching comprising a first current switching circuit (Tr2) having a first input terminal (2) ; a second current switching circuit (Tr3,Tr4) having a second input terminal (5) and a threshold different from that of the first circuit; and a constant current source (Tr1,Tr5,R1) commonly connected to the first and second circuits, complementary input signals being applied to the first and second input terminals.
