Design and performance analysis of low noise amplifier with filters for wban based health monitoring system

In this paper,the design of lna with filters structure is proposed for wireless health monitoring system. the receiver in wireless health monitoring system should have efficient lna as received bio-medical signal should be analyzed very accurately for continuous monitoring of the patient's health. low noise amplifier (lna) plays an important role in communication system to suppress the noise in the received signal. this paper proposes a novel design of lna with band pass filter,butter worth filter and chebychev filter. the proposed lna has been designed using advanced design system tool. the performance of the lna is analyzed for gain,input return loss,output return loss noise figure. the performance of the lna for different filters has been analyzed and it is found out that lna with band pass filter provides good performance compared to lna with butter worth filter and chebychev filters. the proposed lna with band pass filter can be used for health monitoring system for providing accurate received signal. copyright © 2017 all rights reserved.
