<p>A radiation hardening circuit that includes two series-connected transistors that can replace any single transistor in a circuit. The hardening circuit includes a resistor that has a fist node and a second node, a first transistor having a source terminal, a gate terminal, a drain terminal, and a body terminal. The first node of the resistor may be conductively connected t the drain terminal of the first transistor and the second node of the resistor is conductively connected to the body terminal of the first transistor. The hardening circuit also includes a second transistor in series with the first transistor, driven so that both transistors are off or on at any given time. The circuit is resistant to radiation-induced events due to the body bias of the first transistor, the off state of the second transistor, and the current limiting effect of the resistor.</p> |
