The picture a,b,c are voltage generating circuit with temperature compensation.In the picture (a),VD1 and VD2 constitute temperature sensor circuit and it should generate two positive voltage in order to get the positive and negative temperature coefficient.RP1 sets the voltage temperature coefficient from negative one to postive one.Please regulate RP1 to the left and reduce forward voltage of diode VD2 acording to 2mV/℃ proportion and then use A1 to amplify inversely,which can gain + 2 mV / ℃ voltage.In this state,there is a direct current translation.Thus,the stable benchmark voltage moves the negative output voltge to zero voltage.
