Total dose effects in a linear Voltage regulator

Experiments and simulations are used to analyze the total-dose response of a linear voltage regulator. Degradation of the dynamic output range of the error amplifier is determined to be responsible for the regulator failure.

Description
Summary:Experiments and simulations are used to analyze the total-dose response of a linear voltage regulator. Degradation of the dynamic output range of the error amplifier is determined to be responsible for the regulator failure. We present a first-order model to reproduce total dose circuit and system response. Modification of the bias circuitry in the error amplifier using beta compensation techniques is shown to harden the system to a significantly higher total dose level.
