ABSTRACT:
A voltage reference circuit employs a bandgap cell to establish a voltage reference, stabilized relative to the bandgap voltage of silicon, and a compensation circuit for compensating non-linear temperature dependence of the bandgap stabilized voltage reference. A two or three transistor type bandgap cell may be employed to establish the bandgap reference voltage along with a voltage divider network to adjust the output reference voltage relative to the bandgap voltage of silicon. The compensation circuit preferably employs a compensation resistor in the resistor divider network, and a switching circuit for switching current therethrough. This provides empirically determined adjustments to the output reference voltage by switching current through the compensation resistor in accordance with predetermined temperature thresholds.
