Recently, a modulation scheme for modern wireless systems such as 4G long term evaluation (LTE) and mobile Worldwide interoperability for Microwave Access (MiMAX) utilize Orthogonal Frequency Division Multiplexing (OFDM) which has a high Peak-to-Average Power Ratio (PAPR) resulting in degradation of efficiency in transmitters. Therefore, the high efficiency, low cost, compact and high integration Power Amplifier (PA) becoming an important issue in designing a circuit with relatively high power efficiency. Over past years, the PA technology has emerged rapidly and has become highly integrated.
