Abstract
A clock compensation circuit includes a delay circuit configured to generate a plurality of second clock signals by delaying a plurality of first clock signals, a voltage conversion circuit configured to convert phase differences between the plurality of second clock signals into voltages and output converted voltages as a plurality of phase difference voltages, and a comparison circuit configured to generate a plurality of phase difference detection signals by comparing the plurality of phase difference voltages with a reference voltage. The clock compensation circuit also includes a phase error control circuit configured to generate a plurality of control signals for controlling the delay circuit, the voltage conversion circuit, and the comparison circuit according to any of the plurality of second clock signals and the plurality of phase difference detection signals.
