HARMONIC BALANCE VHDL Approach Improves Nonlinear Simulation
Abstract:
icrowave and RF designers have long sought higher levels of performance and accuracy in their simulation tools. Due to the special considerations in the microwave and RF region, there has been a complicated evolution ranging from the application of linear approaches of Touchstone and Simulation Program with Integrated-Circuit Emphasis (SPICE) simulations on nonlinear circuits to more advanced, up-to-date approaches, applying harmonic balance and complex timedomain techniques for fast simulation of nonlinear analog circuits. Fortunately, an approach has been developed to enhance the performance of harmonicbalance simulation through the use of extensions to standard very-high-definition-language (VHDL) models. In the low-frequency area, the SPICE
