  • Patent number: 7486065
    Abstract: The present invention is directed to a device and method for generating a reference voltage. A reference voltage generator comprises a first circuit, a second circuit, and an external device. The first circuit generates a positive temperature coefficient voltage. the second circuit is coupled to the first circuit, biased with a substantially constant current, produces a negative temperature coefficient voltage, and combines the negative temperature coefficient voltage with the positive temperature coefficient voltage as a reference voltage. The external device is coupled to the second circuit, and yields the substantially constant current.
