Abstract :
Asymptotic waveform evaluation (AWE) is a novel method to approximate 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 circuit parasitics. The sensitivities of the poles and zeros show excellent correlation with the perturbation response, and can provide valuable feedback to the circuit designer.<>
