ABSTRACT:
A counter circuit includes Johnson-type counters of m stages, each counter including a plurality of flip-flops connected in a cascade connection, each flip-flop receiving a clock signal at a respective clock input end. In the constitution, signals at respective output ends of flip-flops in a (k-1)-th stage counter are simultaneously input to respective clock input ends of flip-flops in each counter of a k-th stage and more. As a result, it is possible to obtain a signal having an arbitrary ratio of frequency division with high speed, while relatively simplifying the circuit constitution.
