  3. Abstract • This paper presents a novel LNAfor 5.2GHz 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. Introduction • Low noise amplifier is used extensively in modern communication systems. • The LNA uses source inductor degeneration to trade off between the noise and gain.
