ABSTRACT:
A temperature compensation circuit for a device with a voltage output affected by temperature in a predetermined manner and a null output for which the voltage is zero regardless of temperature comprises a voltage to current converter responsive to the generated voltage to produce a proportional current, a current generator comprising elements responsive to the temperature of the device to generate a pair of compensation currents varying therewith in a predetermined manner so that the ratio of the compensation currents embodies a desired temperature compensation, and a transconductance multiplier effective to multiply the proportional current by the ratio of the compensation currents to generate a compensated output current. It may further comprise a current to voltage converter responsive to the compensated output current to produce a compensated output voltage.
