ABSTRACT:
A radiation tolerant electrical component is provided without a radiation hardened material FET. A p-channel MOSFET provides switching capabilities in radiated environments because its gate voltage starts at a negative value and becomes more negative with exposure to radiation. Therefore, the gate is still controllable when exposed to radiation.
