Abstract

Abstract

  • This paper presents a novel LNAfor 5.2GHz applications.


2014 04 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.

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.
