摘要：

A technique is developed whereby the gradient of frequency-domain simulation variables may be analytically determined using time-domain derivative information and the multidimensional fast Fourier transform. It is shown that this technique can be efficiently implemented when a circuit is driven by any number of incommensurate input frequencies. A harmonic balance simulator is constructed which uses this technique to determine the entries of the Jacobian matrix which are needed in a quasi-Newton iteration scheme. A significant reduction of simulation time is observed when compared with a harmonic balance simulator that uses matrix-multiplication-based transforms. © 1990 IEEE
