A power-combined switched-capacitor power amplifier in 90nm CMOS

Abstract

A digitally-controlled switched-capacitor RF power amplifier (SCPA) is implemented with a transformer-based power-combiner in 90nm CMOS. The individual SCPA cores can be controlled to provide high average output power and linearity in an “all-switching” mode or increased dynamic range in a “sequential-switching” mode. The SCPA… (More)
