Abstract
Wireless technology is a growing technology in which lot of attention move towards 2.4 GHz frequency applications. In transceiver front end, power amplifier is an important block of a transmitter. A low voltage power amplifier is proposed using 0.13 µm TSMC CMOS process. In this proposed work, single-ended two stage class AB power amplifier is designed and RF distortion technique is applied to improve linearity. The high linearity low voltage power amplifier is designed and simulated using ADS simulator. The optimised power amplifier produces 18 dB gain, 21.6% PAE, 21.7 dBm of OIP3 and 5.86 mA current consumption at 0.8 V supply voltage. [ABSTRACT FROM AUTHOR]
