ABSTRACT:
A first logic circuit comprises coupling gate circuits driven by clock pulses of different phases, flip-flop circuits cascade-connected via the coupling gate circuits and feedback circuits for feeding back the outputs of the flip-flop circuits to the preceding stage flip-flop circuits, and generates pulse sequences of different phases. A second logic circuit further comprises latch circuits one for each of the flip-flop circuits, driven by the pulse sequences generated by the first logic circuit. Those logic circuits are useful to a successive approximation register of a successive approximation A/D converter.
