Abstract
A skew adjustment circuit comprises a phase adjustment circuit that adjusts a phase of a first input clock based on a predetermined phase control signal, and outputs it as an output clock, a logical circuit that performs a logical operation between signals that are input, an integral circuit that generates a predetermined voltage signal, based on a result of the logical operation by the logical circuit, a comparator that compares an electric potential of the predetermined voltage signal and an electric potential of a predetermined reference voltage signal, a first controller that generates the predetermined phase control signal based on a result of the comparison by the comparator, and a second controller that performs control for selecting a signal that is to be input to the logical circuit. The second controller, in a first mode, performs the control such that the output clock and a second input clock are selected.
