Abstract

A precision voltage reference temperature compensated circuit 10 uses forward biased Zener diodes D2, D4 to provide a negative temperature coefficient compensation circuit and reverse biased Zener diodes D5-D6 to provide a positive temperature coefficient compensation circuit. Use of only Zener diodes results in a circuit 10 with fast recovery to the expected output voltage from transient events such as power supply perturbations, output load switching and/or gamma radiation events. The reference output voltage V.sub.out temperature characteristic is finally established by trimming resistors R3, R4 that are coupled between the current source including transistor Q1 and a positive temperature coefficient compensation circuit of diodes D5-D7. The precision reference output voltage level is finally established by trimming the resistors R5 and R6 that are coupled between the output of the temperature coefficient trim network and ground.
