摘要：

Some important aspects of CMOS RF PA design are discussed. Improving efficiency at circuit level is discussed first, as well as the challenge to achieve high output power in low-voltage CMOS. Next, some PA architectures are reviewed. It will be shown how signal processing can be used to improve the efficiency of a CMOS PA.
