Abstract :
A Class-AB Power Amplifier (PA) integrated circuit for 2.4 GHz is presented. It is designed in SMIC 0.18 μm RF CMOS process. The PA adopts two-stage differential structure. The driver-stage uses cascode structure. In the output-stage common-source structure is employed. The proposed PA provides 24.8 dBm output power with a power-added efficiency (PAE) of 21.2% at 1 dB compression point. It has a small signal gain of 20.6 dB. The simulation results show that under a single 3.3 V supply voltage, the maximum output power reaches to 26.2 dBm. It can be used in IEEE 802.11b/g WLAN. The layout size is 1.4 × 0.75 mm2.
