ABSTRACT:
Any errors arising in a strobed MOS regenerative comparator error amplifier, such as off-set, characteristic changes due to radiation damage, and other circuit changes are corrected by comparing zero inputs for both the unknown and reference signal during a stabilization sample, storing any output signal present when the inputs are zero, in a D flip-flop, integrating the output signal from the D flip-flop and applying the integral back to the error amplifier to oppose the original unwanted error signal so that the output of the regenerative comparator will then be a logical true error signal depending only on the relative magnitude of the unknown and reference signals.
