A simple analog behavioural model for NTC thermistors including selfheating effect

In this paper, a model is presented to simulate loaded, as well as unloaded thermistors with negative temperature coefficients. This analog behavioural model (ABM) is particularly suitable for the steady-state large signal time-domain analysis and design of NTC thermistor circuits, making it possible to simulate complete static current-voltage characteristic of a thermistor element, including the effect of selfheating.
