Abstract
A temperature insensitive voltage reference circuit for use between a voltage supply and an amplifier or comparator reference input is provided having a very small overall temperature coefficient value, approaching zero, over a wide operating range for stabilizing reference voltage with temperature. Preferably, a transistor is connected emitter to ground with its collector designated the circuit output to the reference input. An adjustable voltage divider may be connected between the voltage supply and the circuit output with the intermediate point connected to the base of the transistor.
