Combined Electrical and Thermal Circuit Simulation Using APLAC. Part B.Electrothermal Diode and Transistor

摘要

Numerical diode and transistor simulation models including the effect of self-heating are presented. The models have been implemented in the general purpose circuit simulation tool APLAC that includes the electrothermal interaction properties in its elementary component VCCS. Component models derived from VCCS are available in all elementary analysis modes; no special electrothermal analysis is required. In the electrothermal diode model, all temperature dependencies are made to depend on the dynamic temperature difference. The model of the electrothermal transistor is based on a simple Ebers-Moll equivalent circuit. Examples demonstrating the usage of the electrothermal diode and transisor are given.
