Abstract
A circuit design suitable for use with monolithic semiconductor fabrication techniques which provides two accurate reference voltages, one of which is a certain calculatable percentage greater than, the other of which is the same percentage less than, a fixed reference voltage. The magnitude of this voltage window is set by selection of the value of a single resistor which is connected between a single connection point in the circuit and ground. The two accurate reference voltages are fully compensated for changes in temperature.
