Abstract

This paper presents a novel LNA for 5.2 GHz applications.

• 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.

Low noise amplifier is used extensively in modern communication systems.

The LNA uses source inductor degeneration to trade off between the noise and gain.
