Abstract :
This paper proposes a new pre-distortion linearizer for CMOS power amplifier (PA) to improve the performance of the output 1-dB compression power and power added efficiency at 1-dB compression power. By adopting the proposed pre-distortion linearizer, a 60 GHz cascode PA with 13.7-dBm 1-dB compression power (P1dB) and 14.3% power added efficiency (PAE) at P1dB is demonstrated. The chip size is 0.55 × 0.45 mm2 including all testing pads.
