Abstract
A semiconductor device includes a delay compensation circuit and a bias control circuit. The delay compensation circuit includes a variable delay circuit configured to generate an output signal by delaying an input signal and configured to compensate, according to a first bias control signal, for delay fluctuation caused by fluctuation of a power supply voltage between a first power source and a second power source. The bias control circuit is configured to generate the first bias control signal to compensate for the delay fluctuation.
