Abstract
A temperature compensated voltage reference circuit adapted for on chip location with integrated bi-polar linear circuits, where a temperature stable reference voltage is required in the range of 1.2 to 2.0 volts DC. The circuitry requires only a low chip area and presents a high AC impedance, a low operating current drain, and requires no high value resistors or capacitors.
