About PT100 circuit design

hello,my friends.

Recently, i am designing a circuit with PT100. what the requirements of the circuit are as follows:

Temperature Range: 0-100°C.
output range :1.0000V-1.9999V.
resolution:0.01 °C. or 0.1°C

i have tried a lot of circuits, but thay all donnt work.

could you plz me? thanks for your suggestion.

I read a good article on this ,I think you should check that article ,you will definitely get some help from there. Search on google as Compensates PT100 Transducer you will find that article.That article tells about a characteristics of an PT-100 and It also provides a different expression for the relationship between temperature and resistance for the sensor.

Connect your PT100 in Weight stone bridge format.. get that diff voltage to an diff opamp, then amplify that diff using opamp in differential form then amplify that diff using another opamp as voltage amplifier.

For your ref i have attached file.
