Abstract
In this paper, a simplified nonquasi-static table-based approach is developed for high-frequency broad-band large-signal field-effect-transistor modeling. As well as low-frequency dispersion, the quadratic frequency dependency of the y-parameters at high frequencies is taken into account through the use of linear delays. This model is suitable for applications related with nonlinear microwave computer-aided design and can be both easily extracted from dc and s-parameter measurements and implemented in commercially available simulation tools. Model formulation, small-signal, and large-signal validation will he described In this paper. Excellent results are obtained from dc up to the device f(T) frequencies, even when f(T) is as high as 100 GHz.
