Abstract

A temperature correction circuit for a voltage reference circuit includes two amplifiers, each having an output that controls a respective transistor that produces correction current for adjusting the reference voltage. Both amplifiers include one input coupled in a path to a reference voltage source and another input coupled in a path to a temperature sensing diode circuit. One amplifier's output controls the conductivity of its respective transistor to adjust the reference voltage when the temperature exceeds a high temperature set point. The other amplifier's output controls the conductivity of its respective transistor to adjust the reference voltage when the temperature falls below a low temperature set point.
