Abstract

This paper reviews of high efficiency CMOS class-E power amplifiers (PAs) in gigahertz (GHz) frequencies for wireless applications. The study is focused on the challenges in designing class-E PA especially in GHz frequencies. Problems and limitations in high efficiency class-E PA and the circuits’ topologies are reviewed. Several works on CMOS class-E PA from year 1999 to 2014 are discussed in this paper. Recent developments of CMOS class-E PAs are examined and a comparison of the performance criteria of various topologies is presented.
