Abstract :
Asymptotic waveform evaluation (AWE) is a new method for approximating the behavior of linear(ized) circuits in either the time or the frequency domain in terms of a dominant pole/zero approximation. An efficient method for calculating the sensitivities of the poles and zeros found by AWE has been developed. Using the adjoint sensitivity method, it is possible to inexpensively compute the sensitivities of the poles and zeros with respect to all circuit parameters, as well as to suppressed circuit parasitics. The sensitivities of the approximate poles and zeros found by AWE show excellent correlation with those of the real circuit and provide useful information in both the time and the frequency domain
