Radiation tolerant circuit for minimizing the dependence of a precision voltage reference from ground bounce and signal glitch

摘要

A radiation-hardened reference circuit includes a precision voltage reference circuit for generating a current-controlling voltage at first and second terminals, a driver circuit for receiving the current-controlling voltage at first and second terminals and for generating an output reference voltage, and a differential sampling circuit having first and second input terminals coupled to the first and second terminals of the voltage reference circuit, and first and second output terminals coupled to the first and second terminals of the driver circuit.
