Abstract
An envelope tracking CMOS power amplifier is implemented in 0.18-µm CMOS, and achieves a PAE of 34%, an EVM of 3.2%, and an ACLR of −32.5 dBc at an average output power of 26 dBm and a frequency of 1.8 GHz for a 10-MHz BW 16 QAM 7.5-dB PAPR LTE signal. The envelope tracking operation improves a PAE by 2% to 6.5% over the stand-alone PA for the LTE signal.
