  • Current generating circuit insensive to resistance variation
    Patent number: 6600304
    Abstract: A current generating circuit includes a first resistance inversely proportional current generator, a second resistance inversely proportional current generator, and a current subtractor. The first resistance inversely proportional current generator has a first resistance element, and generates a first current which is inversely proportional to resistance variation of the first resistance element. The second resistance inversely proportional current generator has second and third resistance elements of the same type as the first resistance element, and generates a second current which is inversely proportional to half of the resistance variation. The current subtractor subtracts the first current from the second current to output a constant current regardless of the resistance variation of the first to third resistance elements.
