Power amplifier is the main power consumption block in any advanced wireless communications system. When the DC power is limited, it is crucial to design power amplifiers with high power-added efficiency. The output power and efficiency depends on the active device, bias conditions according to the operating class, matching networks, and so on. The Power Amplifier is the most power-consu!}ling. blpqk among the quil~ing blocks of RF transceivers. It is still a difficult problem to design power amplifiers, especially for linear, low voltage operation. Until now power amplifiers for wireless applications is being produced almost in GaAs processes with some
