Abstract:
A flip-flop circuit includes: a first latch circuit that receives input of a data signal and a rise delay clock signal, raises a signal of a first node according to the fall of the rise delay clock signal, and lowers the signal of the first node according to the rise of the rise delay clock signal; a second latch circuit that receives input of the signal of the first node and the clock signal and lowers a signal of a second node at timing when the clock signal falls; a third latch circuit that receives input of the signal of the second node and the clock signal and generates an output signal for maintaining the data signal; and a pull-down circuit that pulls down the signal of the first node with the rise delay clock signal.
