Problems solved by technology

The output is conditionally discharged according to the input value and the situation of the pull-down topology; in the working process, the clock power consumption of the domino is very large, especially because the node 1 will be frequently charged and discharged; many methods to reduce the power consumption of the domino circuit have been proposed , such as mu

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the drawings.

[0014] Such as figure 2 Shown is a schematic diagram of a domino circuit driven by multiple inputs. The domino circuit driven by an input removes the clock signal. The circuit includes three parts, namely precharge PUN, PDN and an inverter; the precharge PUN is obtained through PDN, according to the PDN branch Number of items, select any one of each branch to control the input data of the NMOS tube, use this input data to control the PMOS tube at the same time, and the PMOS tube is connected in series to become the precharge PUN; the source of the precharge PUN is connected to the power supply voltage, and the precharge PUN The drain is connected to the drain of the PDN; the source of the PDN is connected to the ground; the input of the inverter is connected to the drain of the PDN, and the output of the inverter is used as the output of the domino circuit driven by the input; the gat...

Abstract

The invention relates to input-driven domino circuit design. A domino circuit is structurally optimized, transistors of a clock are removed, and a clock signal is replaced by combined input data, so that dynamic power consumption can be reduced, the number of transistors of the circuit is decreased, the working time is shortened, the circuit performance is improved, and the layout area of the circuit is reduced. According to the input-driven domino circuit design, the problem of high power consumption caused by the clock is effectively solved, and the clock signal is removed from the circuit and is replaced by the combined input data, so that the turn-on and turn-off frequency of the transistors can be greatly reduced, the dynamic power consumption of the circuit is effectively reduced, and the layout area of a chip is reduced.

Description

Technical field [0001] The invention relates to a domino circuit, belonging to the field of circuit design, in particular to an input-driven domino circuit design. Background technique [0002] At present, the level of integrated circuit technology is increasing, the process size of semiconductor devices is continuously reduced, the degree of chip integration is continuously improved, and the functional units that can be integrated on a single chip are continuously increasing, resulting in higher and higher total power consumption of the circuit. In addition, battery-powered portable electronic products are increasingly widely used, such as handheld computers, mobile phones, and notebook computers. The battery power supply time is shortened and the circuit thermal effect is becoming more and more serious. The circuit power consumption has become a key problem in circuit design, especially the power consumption problem of VLSI design has been unavoidable. After the integrated cir...
