A 700-MHz fully differential class-E CMOS power amplifier for wireless applications has been built toward maximum efficiency. The prototype can deliver 1 W of output power in a 50-/spl Omega/ output impedance. The maximum power-added efficiency (PAE) is measured to be 62%. The obtained efficiency and output power is compared with the class-E amplifiers theory.
