Flip-flop circuit

Abstract

The invention provides a flip-flop circuit, and belongs to the technical field of semiconductor integrated circuits. The flip-flop circuit comprises a master latch and a secondary latch driven by clocking signals with same phases; the master latch comprises a first logic module for selectively and at least performing AND logic processing on an input data signal and the clock signal, a second logic module for at least performing NOR logic processing on the clock signal and an output signal of a third logic module, and the third logic module for selectively and at least performing the NOR logic processing on the output signal of the first logic module and the output signal of the second logic module so as to output a result to the second logic module; the secondary latch comprises a fourth logic module for at least performing the NOR logic processing on the output signal of the second logic module and the output signal of a fifth logic module, and the fifth logic module for at least performing the AND logic processing on the clock signal and an inversion signal of the output signal of the fourth logic module. The flip-flop circuit is low in dynamic power consumption.

Description

technical field [0001] The invention belongs to the technical field of semiconductor integrated circuits (ICs), and relates to a trigger circuit for realizing low power consumption. Background technique [0002] With the increasing integration density of integrated circuits (Integrated Circuit, IC) and the continuous improvement of its clock operating frequency, the power consumption (especially the dynamic power consumption) of the IC has drawn more and more attention. Especially for portable electronic devices, their performance and power consumption are a contradiction. Major manufacturers are constantly improving the performance of electronic devices while reducing their power consumption in order to increase the use time of the limited power of portable electronic devices. The application of various high-performance ICs in portable electronic devices is often limited due to high power consumption. [0003] A flip-flop (Flip-Flop) circuit is a basic functional circuit u...

Problems solved by technology

Therefore, regardless of whether the state of the flip-flop changes, as the clock flips, the circuit needs to provide a large amount of power consumption to drive these inverters, transmission gates (or tri-state gates)
