In this paper, a 2-stage low noise amplifier (LNA) is implemented in a 90 nm CMOS technology for 2.4 GHz applications. The measurement results show a noise figure of 3.2 dB with a gain 19.9 dB. The circuit consumes 6 mA from a 1.2 V supply, and has 7.2 mW power consumption. The core size is 1.1 mm × 0.95 mm and the chip size including pads is 1.34 mm × 1 mm.
