Title: Comparator circuit
Inventor: FUJII MASATAKA
IPC: H03F3/45
Filed: 2000-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a comparator circuit of which the rise time of an output voltage can be shortened and of which the speed can be improved. SOLUTION: The output stage of a differential comparator circuit is constituted of the output stage bias part 1 of a constant current circuit and an output part 2 constituted of a switch SW1 and an output signal amplification part, and is connected with a bypass part 3 which is branched from the connection part of the output stage bias part 1 and the output part 2 and is constituted of a switch SW which operates in a phase opposite to the switch SW1 and of a resistor R1. When a comparator circuit output voltage changes from a power voltage to a group potential, the bias current of the output stage bias part 1 is made to flow to the bypass part 3. Thus, the current i5 of the output signal amplification part is constituted only of the discharge current i6 of a load CL.  The transistor size of the output signal amplification part, therefore, can be made small and gate parasitic capacity is reduced. Thus, the response of the output signal amplification part with respect to the input stage output signal can be made faster than a conventional circuit.
