Operational Amplifier Circuit for Linearizing Temperature Readings from Thermistors
James Stockert, E. NAVE · IEEE Transactions on Biomedical Engineering · 1974
An operational amplifier circuit is presented that will provide a linear relation between output voltage and temperature from 10°C to 50°C using a nonlinear thermistor as the temperature transducer. The source of the linearity is discussed and a general method for determining circuit values is described.
