Abstract :
A low-voltage CMOS linear power amplifier (PA) is designed for 2.4 GHz ISM-band short range wireless communication in this paper. A novel adaptive biasing is adopted in the output stage, which dramatically increases the linear output power range as well as decreases the power dissipation at lower output power. The PA is a two-stage configuration and is implemented in 0.35 mum 3.3 V CMOS process. The spectreRF simulation results show that the PA can deliver +25.3 dBm of linear output power with a power gain of higher than 29 dB in -4 dBm input power range.
