该论文提出一种基于变压器的AM-PM失真校正技术，用于28GHz CMOS功率放大器以实现高线性度和高效率。该设计针对5G毫米波通信中对高数据率和高阶调制（如QAM）的需求，在28GHz频段实现了41%的功率附加效率（PAE）和良好的线性性能。
high data-rates, the millimeter-wave (mmW) 5G communication standard will extensively use high-order complex-modulation schemes (e.g., QAM) with high peak-to-average power ratios (PAPRs) and large RF bandwidths. High-efficiency integrated CMOS power amplifiers (PA) are highly desirable for portable devices for improved battery life, reduced form factor, and low cost. To meet simultaneous requirements for high efficiency and reasonable linearity, PAs intended for use with complex modulation are often operated in Class-AB mode [1,2]. For small input amplitude in Class-AB, the device is turnedon and has an input capacitance (Cgs) of ~(2/3)WLCox. As the input amplitude becomes large, the device turns-off for part of the RF cycle, thus reducing its effective input capacitance. This input capacitance-modulation effect creates an
