Design and Analysis of High Gain LNA with Band-Pass Filter for 15.20-17.20 GHz

In this paper Low Noise Amplifier at 16 GHzfrequency designed. this circuit wants to amplify the received signalwhen adding noise as possible.the characteristic of good LNA, largegain, low noise figure (NF) and low power consumption. The LNA isbased on a cascode amplifier using 90nm technology BSIM4 ofADVANCED DESIGN SYSTEM 2014.01. The structure of cascadeamplifier with source inductive degeneration is used.The Chebyshevbandpass filter with passband from 15.20 GHz to 17.20 GHz andBuffer stage in the output of cascade amplifier provide us goodoutput matching so achieving to 15.847db gain up to 21.59dB and0.706 dB of noise figure can decrease to 0.50891dB with stable s11and s22 and use smith chart and stable factor K=1.883 shown in theresult and analysis with Matlab R2015b . Then measurement andconverting S-parameter of design circuit to RLCG model with againused Matlab, NI Microwave Office(AWR)12 and ComsolMulthipysics5.2 to get us a chance to obtain characteristics of thislow Noise Amplifier as a Line Transmission mode, Finally optimizematching and noise and ... by adding inductors.
