RF MOSFET: recent advances and future trends

Recent advances in CMOS processing, continuous scaling of gate length, and progress in SOI (Silicon on Insulator) have stirred serious discussions on the suitability of MOSFETs for RF/microwave applications. This paper covers the recent advances and current status of CMOS as the dominating technology in VLSI, future trend of RF MOSFETs, and applications of MOSFETs in RF electronics. Despite some lingering debates, the prospects for RF MOSFETs with operating frequencies in the lower GHz range are very promising.
