Abstract
A phase interpolator includes a first circuit to generate a first signal having a first phase delay and a second signal having a second phase delay and a phase mixer. The phase mixer is coupled to receive the first and second signals from the first circuit. The phase mixer includes multiple current drivers each including a current driver input coupled to selectively delay one of the first or second signals and a current driver output coupled to output a phase delayed signal. The current driver outputs of the current drivers are coupled together to combine the phase delayed signals from the current drivers to generate an output phase delayed signal having a phase interpolated from the first and second signals.
