Abstract

A low-noise switching voltage regulator for supplying a voltage to a radio frequency (RF) power amplifier is disclosed. In one embodiment, the invention can be conceptualized as a power amplifier supply circuit, comprising a pair of oppositely polarized semiconductor switches, and a data formatter configured to supply a data stream having a voltage transition on at least every other bit to each of the pair of oppositely polarized semiconductor switches.
