A linearized 2.3GHz CMOS power amplifier with AM-AM and AM-PM distortion correction is presented. The varactors are used at the driver amplifier load to correct the phase distortion and gate bias control of the PA to compensate the amplitude distortion. The proposed CMOS PA has been implemented in 0.13µm CMOS technology. The measured results show that P1dB is increased 1.6dB and PAE is improved from 5.5% to 9% at the condition of -28dB EVM, respectively.
