摘要：

A CMOS RF power amplifier that can Change the Output transformer ratio is presented. The CMOS power amplifier is fully integrated in a 0.13 mu m process and has a power added efficiency (PAE) of 38% at 2.1 GHz and an Output power of 30.7 dBm with 3.0 V supply voltage. The PAE at an output power of 16 dBm was increased by 40% by altering the transformer ratio.
