Modulador sigma-delta térmico: aplicação em medição de temperatura.

Abstract

In this work an implementation project of a temperature measurer is presented, the structure is formed by a modulator sigma-delta mono-bit of first order, using a thermo-resistive sensor inserted in its feedback loop. The architecture model from which this project was carried out exposed like all the stages of the development of the circuit implemented. The results obtained from the simulation and the test carried out in the validation of the model used as bases in the development of the project.
