Abstract :
A power amplifier (PA) has been implemented in a standard 0.25 /spl mu/m CMOS technology and shown to deliver 0.9 W output power to 50 /spl Omega/ load with 41% power added efficiency (PAE) from a 1.8 V supply. The PA employs the class-E configuration with finite DC-feed inductance and common-gate switching scheme to achieve high efficiency and not to stress the active devices.
