Abstract

See full text

A current reference circuit includes a voltage generating device, a resistor, one or more diodes, and a thermal bridge including one or more metal alloy contacts disposed on a substrate. The voltage generating device and the resistor have similar temperature coefficients. The diodes are thermally connected to the voltage generating device through the substrate. The metal alloy contacts are coupled between the diodes and the resistor. The diodes form a reverse bias junction when the compensation circuit is energized such that the thermal bridge may provide thermal conduction between the voltage generating device and the resistor.
