Abstract
A circuit for correcting a non-linear output of an electronic temperature sensor due to a non-linear drift over an operating range of temperature. The circuit includes a first circuit portion for adjusting a bias voltage of the sensor to a select initial voltage. The circuit also includes second circuit portion interfacing with the first circuit portion. The second circuit portion comprises at least one electronic element with a non-linear drift over the operating range of temperature, but in a direction opposite that of the drift of the temperature sensor. Thus, the drift of the electronic element alters the bias voltage over the operating range in a manner that compensates (at least partially) for the non-linear drift of the temperature sensor.
