WebMar 28, 2024 · For frequency division, toggle mode flip-flops are used in a chain as a divide by two counter. One flip-flop will divide the clock, ƒIN by 2, two flip-flops will divide ƒIN by 4 (and so on). One benefit of using toggle flip-flops for frequency division is that the output at any point has an exact 50% duty cycle. WebUsing the technique, we add a gate on the clock to get differential Clock and Clock bar, a flip flop that triggers on the Clock Bar rising edge (Clock Neg.) to shift the output of ”B” by 90 degrees and a gate to AND/OR two FF output to produce the 50% output. We get Figure 2, a Divide By 3 that clocks synchronously with 50% output duty cycle.

Check the Q value in the simulator, since the red probably means X, which indicates that the data value of the flip-flop is undefined, which is usually the case after reset. Btw. instead of instantiating a DFFT you could write the flip-flop divider with an always. Also the wire Qn; is not required. Yes the Q value is X.
