Abstract :
This paper describes the feasibility of a power amplifier (PA) in 0.13mum CMOS technology from STMicroelectronics. It is designed for the UMTS W-CDMA standard. This power amplifier provides 33 dBm maximal output power with 60% of power added efficiency (PAE) at 1.95 GHz. This standard requires linearity from -20 dBm till 24 dBm output power. The linear gain is 16.7 dB and the compression point (OCP1) is 28.25 dBm. In order to fulfil UMTS W-CDMA specifications, especially on linearity, the maximum 24dBm of output power required are reached in a linear class of operation.
