Abstract

A phase interpolator includes an adaptively biased phase mixer, phase control circuitry and an adaptive bias generator. The adaptively biased phase mixer has mixing transistor circuitry configured to provide an output phase signal in response to a plurality of phase control signals, a bias current, and a number of phase input signals offset in phase from one another. The adaptively biased phase mixer further has adjustable bias transistor circuitry configured to adjust the bias current provided to the mixing transistor circuitry in response to an adaptive bias signal.
