Abstract :
This paper reports the development of the first 2.4 GHz monolithic-integrated CMOS power amplifier with micromachined inductors. The amplifier is implemented in a 0.24-/spl mu/m CMOS technology. The high-Q (quality factor) micromachined solenoid inductors are fabricated on the surface of the CMOS chip. For 2.5-V operation, the amplifier delivers 20-dBm output power with 31% PAE (power added efficiency) to 50-/spl Omega/ load.
