摘要： A flip-flop circuit includes a first latch, a second latch, and a trigger stage. The first latch is configured to set a first latch output signal based on a first latch input signal and a clock signal. The second latch is configured to set a second latch output signal based on a second latch input signal and the clock signal. The trigger stage is configured to generate the second latch input signal based on the first latch output signal. The trigger stage is configured to cause the second input signal to have different voltage swings based on the first latch output signal and the second latch output signal.
