Abstract
A phase correction circuit includes a plurality of signal paths configured to transmit multi-phase signals. The phase correction circuit further includes a loop circuit coupled to the plurality of signal paths, the loop circuit configured to correct phase skew among the multi-phase signals by averaging the phases of two signals which are obtained by synthesizing a signal of each of the signal paths with another signal of a signal path different from the corresponding signal path.
