摘要

A pulse generating circuit includes a plurality of delay elements cascaded so as to constitute a predetermined loop, wherein when a predetermined input pulse is supplied to a leading end of the series connection, an effective frequency multiplication is applied to signals which appear at a plurality of portions out of the node portions among the plurality of delay elements and the terminal end portion of the series connection by a logical circuit to obtain an output pulse having a higher frequency than the input pulse.
