Abstract
The impact on circuit performance of parameters uncertainties can be effectively evaluated by describing the resulting stochastic problem in terms of orthogonal polynomial expansions of electrical quantities. This contribution formalizes a rule for the construction of an augmented instance of the original circuit, that provides a systematic solution for the unknown coefficients of the expanded variables. The use of SPICE as a solution engine of the augmented circuit provides a convenient and efficient alternative to the conventional approach SPICE uses for uncertainty analysis.Pubblicazioni consigliate
