Abstract
A phase interpolator circuit includes first and second transistors coupled to form a differential pair, a load circuit, a first set of switch circuits, a second set of switch circuits, and a current source. The first set of switch circuits are coupled between the first transistor and the load circuit. The second set of switch circuits are coupled between the second transistor and the load circuit. The current source provides current for the differential pair.
