A New Compact Model for Accurate Simulation of RF Noise in Sub-40nm Multi-finger nMOSFETs

Abstract

A new compact model has been developed in this paper for accurate simulation of RF noise and extraction of actual intrinsic noise in sub-40 nm multi-finger nMOSFETs. This model can predict and verify the excess noise sources before and after deembedding, the mechanism responsible for the complicated layout dependence in various noise parameters, and facilitate optimization design for low noise devices and circuits in nanoscale CMOS technology.
