Single-phase power clock trigger based on electric charge resumption

Abstract

The invention relates to a single-phase power clock trigger based on charge recovering. The trigger comprises an input inverter used for generating two inverse signals and sending the two signals to a charge recovery unit, a cross-coupling charge recovery unit used for reducing the power consumption of a circuit, and a RS trigger used for latching the output of a charge recycling unit, wherein, the input and the output of the inverter are connected with two input terminals of the cross-coupling charge recovery unit respectively; and two output terminals of the cross-coupling charge recovery unit are connected with two input terminals of the RS trigger. The trigger adopts the single phase power clock (similar to a sine wave power) Pclk to complete the function of the trigger D, input and output signals adopt the square wave and can be directly cascaded with a traditional CMOS logic circuit to complete the logic. Compared with a traditional trigger, the trigger of the invention has the advantages that the power consumption is low, and the extremely low power consumption can be realized particularly when the data change rate is low; the number of transistors is small; and the single-phase clock is adopted.

technical field [0001] The invention belongs to the technical field of low-power integrated circuit design, is a charge recovery logic sequential circuit, and in particular relates to a single-phase power clock trigger based on charge recovery. Although it is based on charge recovery logic, it can be directly cascaded with traditional CMOS logic circuits to complete the logic. Background technique [0002] Charge recovery technology, also known as energy recovery or adiabatic circuit technology, is a low-power circuit technology that has emerged in the past ten years. Using this technology can significantly reduce the power consumption of the circuit, and has become a low-power circuit technology. It is a hot spot in the research field of power consumption integrated circuit technology. Using this technology, the power consumption can be reduced to zero in theory, so this technology was originally called adiabatic circuit technology. [0003] To illustrate the advantages o...

AI Technical Summary

Problems solved by technology

The characteristic of the former is that the power consumption of the circuit can be reduced to zero in theory, but the circuit must use reversible logic to complete the function of the circuit. At the same time, it needs more pulse power supply. The circuit structure is complex and the operating frequency is low. It is very difficult to realize, so it is practical The value is not much; compared with the former, the latter has a simple circuit structure, no limitation of reversible logic, and the circuit requires less pulse power, so it is easier to apply

The disadvantage of semi-adiabatic circuits is that the recovery efficiency is not as high as that of fully adiabatic circuits

[0018] Due to the huge application value of semi-adiabatic circuits, the research on semi-adiabatic circuits has been very active in the world in recent years, and many new types of semi-adiabatic circuits have emerged, but most of them are combinational logic units, and the structure of sequential logic units is still relatively small.
