Circuit's FunctionsWhen DC amplifier disorder drift is linear and the disorder drift can be offsetted if this circuit's output is compensated to the circuit.This circuit is different from simple diode compensation circuit,it can freely set benchmark temperature and compensation slope.Thus the whole circuit can be regulated. Circuit's Work Principle Like using ordinary silicon diodes ,temperature sensor can obtain about -2.2MV/℃ variation.OP amplifier A1 moves the positive under reference temperature to zero and it can get +10MV/℃ output when the amplifier amplifies parts to 5 times.
