Using the Non-linear Behavior of the Brokaw Bandgap Voltage Reference Cell to Linearize Resistance Temperature Detectors (RTD)

Using the Non-linear Behavior of the Brokaw Bandgap Voltage Reference Cell to Linearize Resistance Temperature Detectors (RTD)

Resistance temperature detectors (RTD) present second and third order non-linearities, and a linear signal processing circuit which converts the voltage on a Pt-100 RTD to an output voltage with 10 mV/oC presents a maximum non-linearity error of 1.07 oC (10.7 mV) in the 0 to 85 oC temperature range....
