abstract = "Power amplifier (PA) is one of the most power-consuming blocks in a transmitter. It is critical to improve power-added efficiency (PAE) in the design of a PA. This paper presents a 2.4 GHz class-E PA particularly designed with a two-stage architecture. The inverter driver stage outputs a full swing square wave to control the on-off of the power stage. By using cascode self-biased topology in the power stage, the peak drain-gate voltage is reduced and the problem caused by transistor breakdown voltage can be overcome. According to the post-simulated results, the proposed PA provides greater than 35% PAE while delivering adjustable saturation output power (Psat) between 9.3 and 17.6 dBm at the center frequency of 2.4 GHz in 0.13μm CMOS. In the maximum Psat state, the PAE is 40.6% with a 1.2V supply voltage and the optimum load resistance obtained in load-pull simulation.",
