ABSTRACT:
A delay circuit comprises a plurality of delay blocks connected in series, and a driving portion adapted to logically combine signals transmitted by the plurality of delay blocks to generate a delay circuit output signal. Each of the plurality of delay blocks delays an output signal from an immediately previous delay block and transmits a resulting delayed output signal to a next delay block when a delay operation is enabled based on a corresponding control signal. However, where the delay operation of a delay block is disabled based on the corresponding control signal, the delay block transmits the output signal of the immediately previous delay block to the driving portion.
