Abstract
A phase interpolator interpolates between a plurality of clock phases using a plurality of switching legs coupled to a common output. Each switching leg includes a pair of differential switching transistors each having a gate and two additional terminals, one of which is coupled to said common output. The gates are coupled to respective ones of the plurality of clock phases and their complements. Tails couple the other terminals of said switching transistors to ground. Each tail made up of a plurality of transistors. A load coupling the common output to a voltage.
