摘要：
The paper describes a digital approach to adjust (in controlled fashion) the output power of an RF circuit using 0.5um digital CMOS technology. This circuit would serve as power driver that minimizes the wasted power and maximizes the delivered power to the load. The power amplifier consists of an array of parallel NMOS transistors connected to an (all-on-chip) Modified class E Power Amplifier. The overall circuit functions as a direct digital to RF filtered amplitude converter. The results show that the maximum output power achieved is 8 dBm using a 3V power supply and occupying 0.18.um(2).
