Abstract
A timing signal generation circuit according to the present invention includes: a delay circuit for transmitting an input clock signal while delaying the clock signal, the delay circuit having a plurality of intermediate taps capable of outputting the clock signal at their corresponding positions in the delay circuit; a detection delay circuit for transmitting the clock signal while delaying the clock signal, the detection delay circuit having a plurality of intermediate taps capable of outputting the clock signal at their corresponding positions in the detection delay circuit; a plurality of sample/hold circuits each having a sampling signal terminal, the sampling signal terminals being connected to corresponding ones of the plurality of intermediate taps of the detection delay circuit; a plurality of boundary delay circuits for detecting an edge of the clock signal, the boundary detection circuits being connected to respective output terminals of the sample/hold circuits; and an output selection circuit for extracting the clock signal via at least one of the plurality of intermediate taps selected in accordance with an edge position of the clock signal detected by the boundary de…
