Abstract
A 2.4-GHz dual-mode power amplifier with transistor resizing is proposed. The proposed technique keeps the conductance for optimum power-matching constant in both modes. By introducing transformers and capacitors, the 50-ohm load is matched to near-optimal impedances for size-scaling MOS transistors. Using a 0.18-pm CMOS process, the proposed PA demonstrates a PAE enhancement of 2.7×/2.3× respectively at 6.5-dB/9-dB transmitting power back-off. © 2017 IEEE.
