Abstract
A phase rotator control circuit is provided. The phase rotator control circuit is coupled to a phase rotator core and includes a first set of transistors coupled to receive digital control signals. The first set of transistors is coupled to a second set of transistors configured and arranged to form a filtered current mirror. An output of the filtered current mirror is coupled to provide an analog phase control signal to the phase rotator core.
