cuits is approximated using interpolating Fourier series that interpolates
the value of the input of the Volterra circuits at time points of a fixed in-
terval. The sampled-data simulation algorithm for linear circuits is used
to solve the Volterra circuits. In addition, the two-step algorithm for
periodically switched linear circuits is utilized to compute the consistent
initial condition of the Volterra circuits, subsequently, that of periodi-
cally switched nonlinear circuits. Both the response and sensitivity of
periodically switched nonlinear circuits are obtained at equally spaced
intervals of time.
The method achieves superior computational efficiency by avoiding
costly Newton-Raphson iterations. Also, high numerical accuracy is
achieved by employing high-order interpolating Fourier series.
The method is most effective and computationally efficient for periodi-
cally switched nonlinear circuits with mild nonlinearities whose behavior
can be characterized sufficiently using the low-order Volterra series ex-
pansion. For circuits with harsh nonlinearities, such as comparators and
