A method for protecting an electronic circuit having at least one output against external radiation includes functionally duplicating the electronic circuit and linking the outputs of the electronic circuit and the duplicated electronic circuit to homologous inputs of at least functionally equivalent combinatorial or sequential elements. The homologous outputs of all the combinatorial or sequential elements are linked together. The electronic circuit can be duplicated multiple times.

Method for protecting a logic circuit against external radiation and associated electronic device

A flip-flop may include a first master stage for latching data, a second slave stage for latching data, and an input multiplexer circuit receiving, as input, data to be latched in the flip-flop. The multiplexer may have single clock phase. The first master stage may be clocked based upon a clock phase, whereas the second stage may be clocked based upon another clock phase.
