Consider the circuit shown above. The output should be the vote of the three flip flops. The switch to the right lets you inject a failure by selecting the invert output on that one stage ...

In this case, [Tod] wanted to use a momentary tactile switch to turn ... he built the circuit around a 555 timer. What he really needed in this case is a flip-flop but lacking a chip for that ...

Lot of power optimization strategy like power domains creation, usage of additional analog power switch-control circuitry ... Conventional Flip-Flop architecture: Fig. 1 depicts the conventional ...
