CMOS LARGE SIGNAL and RF Noise MODEL FOR CAD

Paper in proceeding, 2006

A compact large-signal model(LS) for high frequency CMOS transistors is proposed and experimentally evaluated with DC, S-parameter, Power Spectrum measurements and load pool measurements. Very good correspondences between measurements on 90 nm CMOS FETs and simulations were achieved. Due to the low number of model parameters and the careful selection of model equations, the model exhibits excellent convergence behavior, a property important for successful nonlinear circuit simulation of RF circuits. The LS model was extended to model the RF Noise and implemented in commercial CAD tool and shows a good correspondence between the measurements and the model
