Abstract: PROBLEM TO BE SOLVED: To provide a clock phase adjustment device that can adjust the phase with high accuracy for a circuit with a greater delay time dispersion in components such as a MOS LSI and even under an environment where temperature fluctuations are greater and to provide a variable delay circuit for the clock phase adjustment device. SOLUTION: The variable delay circuit is configured with transfer gates 101 to 104 and 111 to 114 that select the magnitude of loads. Further, for the variable delay circuit where a selector circuit selects a path with a different delay time, when a path with a short delay time is selected, a path bypassing part of the selector circuit is provided. The above variable delay circuits of two kinds above are employed so as to make the former variable delay circuit follow a temperature change and the latter variable delay circuit adjust a phase difference due to component dispersion. Thus, it is not especially required to provide a high-speed circuit to follow a temperature change during operation and a minimum delay time of the variable delay circuit can be shortened. Thus, the delay time dispersion in the variable delay circuit itself can easily be reduced.
