NARROWBAND/WIDEBAND LNA FOR COGNITIVE RADIO WITH LOW POWER RECONFIGURATION – WIRELESS SENSOR NETWORK

Abstract

This article proposed wireless sensor with low noise amplifier where wideband operations and multiple
narrowband are operated by providing simultaneous input matching and output load reconfigurability
simultaneously. The wideband and narrowband signals are combined and obtained with less noise power.
There are various applications which use this type of signals for various benefits. These are mainly used
in the receivers. Evolution of reconfigurable architecture, multimode input matching and multimode load
network are the steps followed in this algorithm. The noise obtained is less than the existing system. The
designing of receiver with less noise power signals in the physical layer and applications of CR-WSN is to
provide with the requirements to the multiple bands of the spectrum.
