Abstract :
This work presents the design of a monolithically integrated CMOS RF power amplifier for 0.9 - 1.1GHz operating from one single power supply voltage of 0.9V to 1.65V. The amplifier was processed in a 2.5V, 0.25¿m, 4 metal layer standard CMOS process of Infineon with fT = 40GHz. At 0.9V supply voltage an output power of 0.13W (21.2dBm) is achieved with a power added efficiency (PAE) of 37% at 1GHz. At 1.65V supply voltage, the output power is 0.41W (26.2dBm) with a PAE of 31.2% at 1GHz.
