Abstract
A phase mixing circuit includes a first driver comprising 2n inverters configured to drive a first clock signal, where n is a positive integer, and a first selection circuit configured to couple each of the 2n inverters of the first driver to a first mixing node, on the basis of a weight having first to 2nbits. The phase mixing circuit also includes a second driver comprising 2n inverters configured to drive a second clock signal and a second selection circuit configured to couple each of the 2n inverters of the second driver to the first mixing node, on the basis of an inverted signal of the weight.
