Abstract
Emitter-coupled differential amplifier transistors have their collector currents differentially combined for application to a series regulator transistor in series with a potential divider network having first and second taps to the base electrodes of the emitter-coupled differential amplifier transistors, for completing a feedback loop which develops positive-temperature-coefficient voltages across resistor portions of the potential divider network. These positive-temperature-coefficient voltages augment negative-temperature-coefficient voltages developed across semiconductor diode means included in the potential divider network to provide for zero-temperature-coefficient voltages being developed across the potential divider network or a portion thereof.
