A 2.4-GHz silicon-on-sapphire CMOS low-noise amplifier

A low-noise amplifier operating at 2.4 GHz has been fabricated with MOSFETs in silicon-on-sapphire technology. The amplifier has a 2.8-dB noise figure, 10-dB gain, and 14-dBm output referred IP3 with 14-mW power dissipation. The amplifier was matched for minimum noise with on-chip spiral inductors and capacitors.
