Modeling and Simulation of a Wheatstone bridge Pressure Sensor in High Temperature with VHDL-AMS

Sahbi Baccar, Timothée Levi, Dominique Dallet, François Barbara
Abstract:
This paper presents a model of a Wheatstone bridge sensor in VHDL-AMS. This model is useful to take into account the temperature effect on the sensor accuracy. The model is developed on the basis of a resistor model. Simulations are performed for three different combinations of parameters values. They confirm the resistors mismatch effect on the sensor accuracy in high temperature (HT).
