Abstract:
1. A radiation tolerant component for providing controlled electrical response in radiation-intensive applications comprising: At least one non-radiation hardened P-channel FET switching transistor, the transistor having a gate, a drain, and a source; a voltage source, said stored voltage source, having a positive terminal and negative terminal; and an inverter, said inverter having a positive and negative terminal, said voltage source, and said inverter being in series with the gate of the transistor, whereby the transistor is the sole principle power switching device of a radiation tolerant high-power DC/DC converter, the FET operating close to the maximum gate voltage signal so that higher signals handle higher radiation levels and the FET functions across a large range of radiation exposure handling high radiation levels, whereby said radiation tolerant component produces a gate drive signal in a range that is high enough to saturate a drain to source channel of the FET but not so high as to exceed a gate-to-source breakdown voltage rating of the FET.
