Abstract
A change pump circuit included in a clock synchronizer is capable of preventing occurrence of an offset even though an output potential of a loop filter is varied, and includes a control circuit controlling a gate potential of a transistor such that predetermined constant current flows through the transistor connected between the line of a power-supply potential and an output node of the loop filter by a switching circuit, based on the output potential of the loop filter.
