A single-chip linear CMOS power amplifier for 2.4 GHz WLAN

Abstract

A single-chip linear CMOS PA for OFDM WLAN applications adopts a fully differential topology with transformer-type output matching and operates from a 3.3V supply. All of the components, including the input balun and output transformer, are integrated on a single 0.18mum CMOS die and no off-chip component is required
