Modularized Analysis and Design for Low Noise Amplifier Using the Equivalent Noise Model Method

WANG Jun(Institute of Electronic Engineering,China Academy of Engineering Physics,Miannyang 621900,China)  
Based on the equivalent noise models of two port network,this paper improves effectively the design accuracy of low noise amplifier via using the complete E n—I n noise model of active devices obtained by the precision measurement;and the noise estimation process is simplified via using the modularized analysis and design of noise network achieved by researching into the spectral relations between the E n—I n model and the other six kinds of equivalent noise models.It is desired to exploit the CAD software based on research here for low noise optimum design of complex circuits,and to make it with the advantages such as standard,high universality,high accuracy and fast calculation.The experiment proves the effectiveness of the method here.
