ABSTRACT:
A circuit and method for reducing the variation of a reference voltage as a function of resistivity ρ in a current-mode bandgap reference circuit generating a reference current that is applied to an output resistor to generate the reference voltage. According to the invention, a substantially constant current is generated and added to the reference current.
