A Broadband Mixed-Signal CMOS Power Amplifier With a Hybrid Class-G Doherty Efficiency Enhancement Technique

Abstract

This paper presents a broadband mixed-signal CMOS power amplifier (PA) with a hybrid Class-G Doherty architecture for PA efficiency enhancement up to the deep power back-off (PBO) region. Our proposed mixed-signal linearization technique ensures the PA's amplitude modulation (AM)-AM linearity by digital PA operation and suppresses the PA's AM-phase… (More)
