DESIGN AND IMPLEMENTATION OF CMOS LNA FOR BLUETOOTH AND BLE APPLICATIONS

Abstract

Low Noise Amplifier (LNA) is an important component of transceivers and is also widely used in wireless applications. LNA is the first active element in the receiving chain. Its NF and gain play a significant role in the overall performance of the receiver.With the increasing need for the Internet of things (IoT), Bluetooth low energy (BLE) technology has become a popular solution for wireless devices. When compared to classic bluetooth, BLE has an advantage of low power consumption. Hence it will be apt for IoT based applications. BLE may replace Bluetooth as it is ought to have a low power consumption which gives BLE an upper edge over Bluetooth. We will study the different topologies used to implement LNA for BLE applications and analyze their performance parameters. Our aim is to design an LNA which is able to provides better performance in terms of all parameters and is apt to be used in Bluetooth and BLE applications. We perform all the simulations in Advanced Design System(ADS).
