Abstract:
A temperature compensated current source forms an uncompensated source current that is proportional to a reference voltage applied to an impedance, wherein the impedance varies with temperature. A temperature compensation current is formed that is proportional to absolute temperature (IPTAT). The uncompensated source current and the temperature compensation current is combined to form a temperature compensated source current and provided as an output of the current source.
