Abstract

This paper presents a reconfigurable multi-band class E power amplifier designed in CMOS technology. The proposed class E power amplifier operates efficiently over sparsely separated frequency bands by switching the capacitance of the load network. Simulation results showed a stable and high power added efficiency of 60% with 18.5dB gain, and 83% with 14.5dB gain for 2.4GHz and 5GHz WLAN applications, respectively.
