3. Abstract This paper presents a novel LNA for 5.2 GHz applications.

4. The fully integrated 5.2GHz LNA exhibits 15dB maximum gain, 2dB minimum noise. The LNA produces a 1-dB compression output power of -16 dB m. It consumes 5mA current from a supply voltage of 1.8V.

5. Low noise amplifier is used extensively in modern communication systems. The LNA uses source inductor degeneration to trade off between the noise and gain. Introduction
