Abstract
Disclosed is a closed-loop feedback system for controlling the soft error rate (SER) due to radiation strikes on electronic circuitry. A variable sensitivity soft error rate detector provides and output corresponding to the soft error rate. This output is supplied to a voltage control. The output of the voltage control is fed back to the sensitivity control of the sensor—thus forming a feedback loop. The output of the voltage control may be the power supply of the soft error rate sensor. The output of the soft error rate sensor may also be used to enable and disable fault tolerant schemes or alert a user.
