A 2.45GHz 0.18µm RF CMOS Class-AB power amplifier (PA) with high linearity and output power for WLAN is presented in this paper. The proposed power amplifier is implemented with a two-stage architecture which is followed by an off-chip output matching network. To improve the linearity, an integrated diode linearization circuit provides a compensation mechanism for the input capacitance variation of the active devices, improving the linearity from the gain compressing. Moreover, a simple LC… CONTINUE READING
