Abstract

Although technological scaling is benefical for CMOS ICs for digital applications, it impacts seriously on analog and radio frequency circuit performances. In this scenario, this paper investigates power loss mechanisms in Class-E power amplifiers highlighting their depedencies on technological scaling. An analytical model describing PA power added efficiency is obtained, and its results are validated against circuit simulations. Scaling effects on efficiency are modeled and discussed, showing that Class-E PA performance are not significantly affected by scaling when delivering low-medium output power, contrarily to what is commonly believed.
