ABSTRACT:
A radiation-hardened logic circuit prevents SET-induced transient pulses from propagating through the circuit, using two identical logic paths. The outputs of the two logic paths are fed into an exclusive-OR gate, which controls gating circuitry. The gating circuitry can be a controlled pass-gate circuit and a data latch, an adjustable threshold comparator, or two controlled latches. Transient pulse suppression is achieved with less circuitry and expense than is found in TMR circuits.
