摘要
A new analytical approach to extract high frequency MOSFET noise is presented and its validation is carried out with careful comparison with numerical physics-based 2D noise simulations. The analytical formulation accounts for drain and gate noise spectra and their correlation, and extends the classical van der Ziel approach to short channel devices. The field dependency of the diffusivity is shown to affect the noise performances significantly in short-gate devices. The new model is well suited to be exploited in circuit simulation in conjunction with compact models such as BSIM4.
