摘要

This paper presents a high power and highly efficient 5.8 GHz differential two-stage cascode Class-A Power Amplifier (PA) for a Wireless Power Transfer (WPT) system. The PA is designed in a standard General Purpose (GP) 180 nm CMOS technology. The process does not apply any Radio Frequency (RF) devices such as inductor nor transformer which are essential for an RF design. A full custom-made transf...
