Abstract :
A 900-MHz single-stage low noise amplifier (LNA), requiring one external inductor and matched to 50-Ω at both the input and output, has been implemented in a standard digital 0.8-μm CMOS technology. Measured noise figures for the LNA in package are 2 dB at 6.2 mW, 1.78 dB at 8.1 mW, 1.5 dB at 13.2 mW, and 1.2 dB at 30 mW. At 30 mW and VDD=3.0 V, the LNA has a power gain of 14.5 dB, and an IIP3 of -1 dBm. At 6.2 mW and VDD=2.7 V, the LNA has a power gain of 9.4 dB, and an IIP3 of -3.8 dBm
