Abstract :
In this presentation, we are offering a new approach to handling circuits with nonlinear devices. Instead of regular biasing this method presents a way to localize the biasing by using "port nullification". The method is built around the concept of additivity, a property of superposition that has been widely used in linear circuits. This method allows the circuit designer to select a scheme of applying dc (or ac) sources in multiple steps to better control the dc operation of the circuit and get faster convergence. The method is tested through some examples and by using SPICE simulator
