Tantalum and Niobium Oxide Capacitors Equivalent Circuit Model Applicability to Simulation Software
Real world passive components have not been used in creating models for circuit simulation software. Ideal passive components (resistors, capacitors, inductors) are routinely used in simulation software. Unfortunately, ideal and real passive components have significant differences in their electrical parameters. These differences lead to inaccuracies between actual hardware performance and expected results based upon software simulation programs.
This paper will describe the development of equivalent circuit diagram for real capacitor behavior. Use of this real world model in simulation software will guarantee an accurate simulation response in developed circuit diagram.
The model, which is presented, includes real component behavior for Tantalum and Niobium Oxide capacitors. Tantalum and Niobium Oxide components are slightly dependent with temperature and thus the article will describe model structure with temperature dependences.
