  • Current bandgap voltage reference circuits and related methods
    Patent number: 6563371
    Abstract: A bandgap voltage reference circuit and related method characterized in having a first current source for generating a first current having a positive temperature coefficient, a second current source for generating a second current having a negative temperature coefficient, and a resistive element to receive both the first and second current to develop a reference voltage. By configuring the circuit such that the magnitudes of the positive and negative temperature coefficients are substantially the same, the reference voltage becomes substantially invariant with changes in temperature. Another circuit is provided in conjunction with the voltage reference circuit to substantially equalize the drain-to-source voltage of the transistors used in the voltage reference circuit.
    Type: Grant
