A CMOS Power Amplifier With a Built-In RF Predistorter for Handset Applications
IEEE Transactions on Microwave Theory and Techniques（2012）
摘要
A CMOS power amplifier (PA) with a built-in RF predistorter is proposed to improve the predistortion system efficiency, especially for handset applications. To eliminate the power consumption of an external predistorter and digital-to-analog converters in the control signal paths, the driver stage of the proposed PA has gain and phase control abilities according to two digital control words. This ...
