Abstract

A radiation tolerant discrete reference voltage source includes just two bipolar junction transistors, five resistors, and a Zener diode. Two of the resistors form a voltage divider that outputs a reference voltage. Values of the resistors included in the voltage divider can be selected to output a desired reference voltage level, for example, 5.00V, 4.00V, or 2.50V, which obviates a need to procure unique voltage references for those reference voltage levels and provides design flexibility. The radiation tolerant discrete reference voltage source provides improved control over radiation hardness and does not require high gain transistors. Because relatively few, inexpensive components are used, the radiation tolerant discrete reference voltage source can be produced at a low cost.
