Abstract
A circuit employing one operational amplifier, one dualjunction field-effect transistor, four resistors, and two potentiometers is used to produce a voltage output proportional to the quantity t when the input voltage is related to t by at + bt2, where a and b are constants. The useful operating voltage range, the maximum value of bt/a that can be accommodated, the accuracy of the linearizing process, and the effects of changes in the ambient temperature on the circuit are considered.
