This work proposes a "dynamic biasing" technique and uses on-orbit simulations with experimental testing to demonstrate up to a 16x improvement in total-dose lifetimes for COTS devices without additional shielding or modifications to the chip. Building upon this foundation, the dynamic biasing technique offers a unique opportunity for microelectronic systems to begin intelligently responding in real-time to their radiation environment. We believe this fundamental technique can become an integral tool to countless future electronic systems in space.
