Pulse-Width Modulated CMOS Power Amplifiers

M odern wireless communications systems are now being almost fully integrated into radio frequency (RF) systems-on-chip (SOC). The power amplifi er (PA) is currently the gating element to the realization of a full complimentary metal-oxide-semiconductor (CMOS) RF-SOC solution due to its relatively poor performance when compared to counterparts designed in III-V compound semiconductor technologies. CMOS suffers in comparison for two main reasons: 1) Scaling of
