Abstract:
A universal temperature compensation circuit for use with a temperature sensor operative to generate an analog temperature signal based on the temperature thereof. The universal temperature compensation circuit comprises an analog to digital converter in electrical communication with the temperature sensor. The analog to digital converter is operative to generate a digital temperature signal from the analog temperature signal. In electrical communication with the analog to digital converter is an electronic storage device containing digital data correlated to temperatures of the temperature sensor. The universal temperature compensation circuit further includes a digital to analog converter in electrical communication with the electronic storage device. The digital to analog converter is operative to generate an analog voltage level from the digital data contained within the electronic storage device. An amplifier is in electrical communication with the digital to analog converter and is operative to buffer and generate a final output voltage level from the analog voltage level.

Abstract:
A three input comparator facilitates the comparison of a signal to the greater of two different reference voltages in a manner which mitigates propagation delay. A first differential pair of transistors facilitates comparison of the two reference voltages to one another, while second and third differential pairs of transistors facilitate comparison of the signal to the higher of the two reference voltages.
