Abstract
This work presents the development of a Matlab software tool based on a non-iterative method for the nonlinear analysis of Bulk Acoustic Wave (BAW) resonators and filters. The procedure starts with the admittance matrix extraction of the distributed circuit that models a resonator. The aim of this procedure is to avoid high computation times and/or convergence problems that usually appear when performing Harmonic Balance (HB) simulations of very large circuits, as those resulting from a distribu...
