  • RADIATION-HARDENED D FLIP-FLOP CIRCUIT
    Publication number: 20210257999
    Abstract: A flip-flop and latch circuit is disclosed. The circuit includes a single-input inverter, a dual-input inverter, a single-input tri-state inverter, a dual-input tri-state inverter, and two single-event transient (SET) filters. The single-input tri-state inverter receives an input signal D. The dual-input tri-state inverter includes a first input, a second input and an output, wherein the first input receives output signals from the dual-input inverter and the second input receives output signals from the dual-input inverter via the first SET filter. The output of the dual-input tri-state inverter sends output signals to a first input of the dual-input inverter and a second input of the dual-input inverter via the second SET filter.
