摘要：

The Thermal Sigma-Delta (T Sigma Delta) modulator is a thermal-electric system where the resistive element performs in the thermal domain part of the Sigma Delta modulator (sum and integration). In this work, we propose the modeling and we perform simulations of 1st and 2nd order T Sigma Delta modulators using bolometers as the thermal-electric device. This study has the purpose of achieving a complete solution of a bolometer with increased sensitivity, while providing a digital output, using only thermal sigma-delta converters, which is suitable solution to integrated transducers.
