Abstract

In this paper a new analog behavioral model of a negative temperature coefficient thermoresistive sensor developed using SPICE for a hot-wire Wheatstone-Bridge Constant Temperature Anemometer is proposed. The analog model was developed using a capacitor and voltage and current dependent sources. This model is suitable for transient and steady-state time domain analysis. Sensor´s behavior is detailed and an example of employment in a Wheatstone-Bridge Constant Temperature Anemometer architecture is presented. The validation is made through simulation, results of which are presented and discussed.
