IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT
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.
