Abstract :
This paper presents a sub-mA, low-noise, high-gain CMOS low noise amplifier (LNA) for 2.4-GHz band applications based on 0.18 mum CMOS technology. Low-noise under power-constrained can be achieved by using an inductive cascode degeneration amplifier with an extra gate-source capacitor. Gain enhancement can be obtained by using capacitive feedback at the cascode transistor. Measurements show 16 dB gain, 1.8 dB NF, -10 dBm IIP3 while dissipating only 0.5 mA from 1.5 V supply
