Abstract
Feedback circuits with thermoresistive sensors have been widely used in the measurement of thermal radiation and quid flow. In general, the operation of these circuits is explained, assuming an ideal operational amplifier use d in the feedback configuration. The effect of the operational amplifier of fset voltage on the static performance has been analyzed. The error introdu ced when used as a measuring instrument, due to input offset voltage, is es timated.
