ABSTRACT
High efficiency amplifier architectures are critical in modern communication systems. Third generation cellular systems and the upcoming LTE (Long Term Evolution) networks will continue to demand increasing transmitter efficiency and lower cost. In addition, linearity demands will be more stringent in order to meet the required spectral efficiencies, and the high bit throughput required by network users.
