Abstract: A temperature compensation system and technique requiring no measurement of actual temperature differential and wherein each source of thermal error in an electronic circuit can be corrected in addition to overall thermal error. Two reference voltages are provided having equal and opposite temperature response and having a null value at selected normal temperature. A respective correcting voltage is derived from the two reference voltages for each source of thermal error and each of magnitude and polarity to compensate for the corresponding thermal error. A correcting voltage can also be derived for compensation of overall residual thermal error.
