Abstract

LNA is the first element of building blocks of any Wireless receiver. It amplifies the upcoming signal without adding much noise and distortion. In this paper, design and analysis of four different LNA (Low noise amplifier) is presented using Agilent CMOS14 .5μm and .4μm process. Here, C-S degeneration, Current Mirror, Cascade, Cascade and Feedback technique are used for LNA design. The performance evaluation is carried out for first three Narrowband LNA having frequency band 2.45 GHz to 2.85GHz for Bluetooth application and fourth LNA having frequency band 3.1 GHz to 10.6 GHz for IR-UWB receiver application i.e. Wideband LNA. The simulation is done on software ADS2010. The analysis results- the best gain S21 between first three LNA is 21.10dB , input reflection coefficient S11 is -23.71dB, output reflection coefficient S22 is -9.10dB and noise figure is 2.03dB with 2.5V supply are unconditionally stable with stability factor 7.11at 2.85GHz. The fourth LNA having gain of 12.4dB, S11 is -15.5dB, S22 is -10.64dB and noise figure is 2.6dB with 2.5V supply is unconditionally stable with stability factor 7.11at 2.85GHz.
