Abstract:
A semiconductor integrated circuit comprising:a logic circuit which includes first to third pass-transistor circuits,wherein each of said first to third pass-transistor circuits has,a first input node,a second input node,an output node,a first field effect transistor having its source-drain path coupled to the first input node and the output node, anda second field effect transistor having its source-drain path coupled to the second input node and the output node,wherein the first field effect transistor of said second pass-transistor circuit has its gate responding to a signal provided on the output node of said first pass-transistor circuit,wherein each of the first field effect transistor and second field effect transistor of said third pass-transistor circuit has its source-drain path coupled to the first input node of said second pass-transistor circuit,wherein an input signal supplied to each of the first and second input nodes of each of the first to third pass-transistor circuits is logically variable,wherein the first input node and the second input node of said first pass-transistor circuit are respectively supplied with an input signal and another input signal, that are logically independent from each other,wherein the first and second field effect transistors of said first pass-transistor circuit have their gates responding to first complementary input signals and become conductive in a complementary fashion,wherein the first and second field effect transistors of said second pass-transistor circuit have their gates responding to second complementary input signals and become conductive in a complementary fashion, said second complementary input signals comprising a signal in phase with a signal provided on said output node of said first pass-transistor circuit and a signal complementary thereto, andwherein the first and second field effect transistors of said third pass-transistor circuit have their gates responding to third complementary input signals and become conductive in a complementary fashion,further comprising an amplifier circuit which couples to source-drain paths of the first and second field effect transistors of said first pass-transistor circuit.
