ABSTRACT:
A voltage linearization circuit for use with a resistance thermometer device or a thermocouple to produce a nearly linear output signal from a non-linear input signal. The circuit produces a voltage proportional to the square of the input voltage through the use of operational amplifiers and field-effect transistors connected in voltage dividing arrangements, and combines this second order voltage, or a reduced magnitude thereof, with the original input voltage to produce a nearly linear output signal.
