ABSTRACT:
A delay circuit comprises: N-stage circuits having a first circuit to an N-th circuit connected in cascade, the input signal being input to the first circuit and a transmission signal delayed by a (k-1)-stage (where 2≦k≦N) circuit is input to a k-th circuit for sequential transmission; a common delay circuit for delaying the transmission signal of each stage commonly; and path control means for controlling a path of an i-th (1≦i≦N) circuit so that during a predetermined period from an edge timing of a signal input to the i-th circuit to an edge timing of the transmission signal delayed by the common delay circuit through the i-th circuit, the common delay circuit is connected to a signal path, and during the other period, the common delay circuit is disconnected from the signal path, wherein the delayed signal passing through the common delay circuit N times is generated.
