Abstract
A phase interpolator includes: a digital-to-analog converter to generate bias signals associated with phase signals; a multiplexer having an input interface and an output interface, wherein the digital-to-analog converter is coupled to the input interface of the multiplexer; a first current source; and a second current source; wherein the digital-to-analog converter is configured to provide bleeder current signals to the first current source and the second current source while bypassing the multiplexer.
