ABSTRACT:
A flip-flop circuit which has a low power requirement and is capable of high-speed operation has first and second latch circuits having respective clock input terminals connected respectively to inverted- and normal-phase clock input terminals, a pair of differential data input terminals connected respectively to the differential signal input terminals of the first latch circuit, a pair of differential output terminals connected respectively to the differential signal output terminals of the second latch circuit, and a power supply and a current source, each connected to the first and second latch circuits. Each of the first and second latch circuits has first and second current mirror circuits energizable by the power supply, and first through fifth MOS transistors, each of the first and second latch circuits being of a dynamic type.
