Abstract
Multiple multi-stage delay circuits each have n (n is an integer) output terminals. The multi-stage delay circuits each apply delay times to a corresponding input signal, and output, via n output terminals, n delayed signals to which different delay times have been applied. Multiple inverters invert the respective input signals. The multiple multi-stage delay circuits and multiple inverters are alternately connected in the form of a ring.
