Abstract
In this paper, a fully integrated, differential, common gate class-E power amplifier with capacitive cross-coupling is proposed for wireless applications at 2.4 GHz. Capacitive cross-coupled (CCC) common gate structure enhances the power added efficiency (PAE) and reduces the total harmonic distortion (THD) of the circuit. The power amplifier, implemented in UMC 180 nm technology, is designed without series harmonic rejection tanks and uses dc feed inductor. Post-layout simulations with corner analysis are performed in Cadence Virtuoso tool. The power amplifier achieves a maximum PAE of 52%, output power of 18 dBm and third harmonic distortion of −25 dBm for 1.8 V supply.
