Radiation hardened flip-flop circuit for mitigating single event transients

A method for blocking a single event transient (SET) in a flip-flop circuit, the method comprising:

• sending, by a C-gate element, a first signal to a feedback inverter, wherein the C-gate element includes a C-gate input and a C-gate output;
• sending, by a blocking inverter, a second signal to the feedback inverter, wherein the blocking inverter includes a blocking input and a blocking output, and wherein the blocking input of the blocking inverter and the C-gate input are both coupled to a delay output of a delay circuit;
• comparing, by the feedback inverter, the first signal with the second signal, wherein a feedback input of the feedback inverter is coupled to the C-gate output of the C-gate element and the blocking output of the blocking inverter;
• and
• in response to determining the first signal and the second signal are different from one another, blocking the first signal and the second signal from passing to the C-gate element and the delay circuit.
