Design of narrowband 2.69GHz CMOS low-noise amplifier for WiMAX application

Abstract

In this paper, a radio frequency (RF) 2.69 GHz CMOS low-noise amplifier (LNA) for WiMAX applications is presented. WiMAX gives a modern approach to wireless communication with better throughput and larger area coverage. Earlier, 2.69 GHz frequency was allotted to satellite communication and military communication in India. Later to maximize the use of this frequency band, telecom regulatory authority of India set this band to WiMAX application aimed to use in smart cities for high-speed internet connectivity. The output results show that the proposed LNA has the forward gain of 27.7 dB, IIP3 of −1.81 dBm, the noise figure of 1.44 and the 1 dB compression of −10.88 dBm and IIP3 is −1.81 dBm at 2.69 GHz frequency. The power consumption of the proposed amplifier is 18.06 mW at 1.5 V power supply. The design and simulation of proposed LNA is carried out using Cadence Virtuoso analog and digital system design tools of gpdk 45 nm CMOS technology.
