A Survey on Ultra Wide Band and Narrow Band Low Noise Amplifiers for Wireless Transceivers

Abstract

This paper presents the survey of the design of Low Noise Amplifier (LNA) for different wireless applications. This paper focuses diverse design techniques and new architectures in the design and implementation of low noise amplifier such as self-biased, forward bias, common source cascade, Cascode, body bias and LNA based on dual resonance techniques. These design methodologies are serving to reduce the power consumption and enhance the performance such as gain and noise factor in wireless applications. In this paper, recent design methodologies of different LNA is meticulously analyzed and new design method will be proposed to enhance the performance of the LNA.
