ABSTRACT:
Majority voting between triple redundant integrated circuits is used in order to provide an SEU hardened output signal. Accordingly, an input signal is processed in a predetermined manner to provide a first signal, the input signal is processed in the same manner to provide a second signal, and the input signal is also processed in the same manner to provide a third signal. A majority vote is taken between the first, second, and third signals by an SEU immune majority voter circuit, and an output signal is provided corresponding to the majority vote.
