Nexxim Simulator > Nonlinear and Linear SolversHarmonic balance applies Kirchhoff’s Current Law (KCL) at each node for each independent frequency, then solves the nodal equations supplied by the device models in the frequency domain, yielding the steady state frequency spectrum at every node and every branch. In this way the frequency spectrum for all the currents at each node is “balanced”. The algorithm combines a nonlinear solver with a linear solver. As illustrated in Figure 1, the nonlinear solver is an outer loop that arranges the equations so that they can be solved with a linear solver in an inner loop. Figure 1.
