Abstract
A phase interpolator circuit includes differential pairs of transistors, current source circuits, and a transimpedance amplifier circuit. Each of the current source circuits is coupled to provide current through one of the differential pairs of transistors. The transimpedance amplifier circuit converts the current through the differential pairs of transistors into a voltage signal.
