Abstract
There is provided a timing generator generating a timing signal of a predetermined period. The timing generator includes a set/reset latch, a set unit supplying the set signal, and a reset unit supplying the reset signal, in which the set unit includes: a first variable delay circuit that delays a given reference clock to output a first set signal; a second variable delay circuit that delays the given reference clock to output a second set signal having a phase different from the first set signal; an OR circuit that computes a logical sum of the first set signal and the second set signal to generate the set signal; and a third variable delay circuit that delays the set signal output from the OR circuit to adjust a skew between the set signal and the reset signal.
