Adiabatic switching is an approach to low-power digital circuits that differs fundamentally from other practical low-power techniques. When adiabatic switching is used, the signal energies stored on circuit capacitances may be recycled instead of dissipated as heat. We describe the fundamental adiabatic amplifier circuit and analyze its performance. The dissipation of the adiabatic amplifier is compared to that of conventional switching circuits, both for the case of a fixed voltage swing and the case when the voltage swing can be scaled to reduce power dissipation. We show how combinational and sequential adiabatic-switching logic circuits may be constructed and describe the timing restrictions required for adiabatic operation. Small chip-building experiments have been performed to validate the techniques and to analyse the associated circuit overhead 相似文献

This paper investigates the power-clock generation using Step Charging Circuits (SCC). In particular, the impact of the adiabatic load on the energy dissipation of the 4-phase Power-Clock Generator (PCG) and on the overall adiabatic system is investigated. The adiabatic implementations are compared with their conventional CMOS counterparts based on energy dissipation, the number of transistors and operation time. The simulation results show that the area (number of transistors) influences the energy dissipation of SCC. Operation time affects the energy dissipation of the controller and degrades the energy benefits obtained in the energy dissipation of SCC and adiabatic core. Lastly, the impact of a number of steps on the energy efficiency of the 4-phase PCG is investigated. We compare the energy efficiency of the 4-phase PCG using 2-step, 3-step and 4-step charging circuit with the energy efficiency of the existing 4-phase PCG with and without resonant inductors. 相似文献

This paper presents an analytical model to study the scaling trends in energy recovery logic. The energy performance of conventional CMOS and energy recovery logic are compared with scaling the design and technology parameters such as supply voltage, device threshold voltage and gate oxide thickness. The proposed analytical model is validated with simulation results at 90 nm and 65 nm CMOS technology nodes and predicts the scaling behavior accurately that help us to design an energy-efficient CMOS digital circuit design at the nanoscale. This research work shows the adiabatic switching as an ultra-low-power circuit technique for sub-100 nm digital CMOS circuit applications. 相似文献

With the emergence of various battery operated technologies in different computing domains and the challenge of heating in such technologies, the issue of energy dissipation has become more critical than ever before. In such systems, energy constraints in one hand, and heat generation, on the other hand, necessitates the employment of energy efficient technologies in the fabrication of digital circuits. One possible solution for mitigating the energy dissipation in digital circuits is the use of adiabatic families in the process of designing computing devices. Adiabatic circuits are designed mainly based on the principles of thermodynamics and provide a paradigm shift in the design of digital systems. Nevertheless, their impact on the reliability of digital circuits due to susceptibility to soft errors has not been explored comprehensively. In this paper, we first try to survey some existing adiabatic logic families. Then we attempt to evaluate their reliability by validating their functionality under the effect of soft errors. Our evaluations which were conducted on a set of SPICE simulations have shown that amongst SCRL, 2LAL, RERL, PFAL, 2N2N2P and ECRL families the ECRL family is able to tolerate more than 90% of the injected transient faults and the applications with a high demand of reliability can use this family of adiabatic circuits. Furthermore, we will propose some suggestions for establishing reliable computations through adiabatic circuits. 相似文献

This paper presents a strategy for minimizing non-adiabatic dissipation in adiabatic arithmetic units. The non-adiabatic dissipation is minimized by architectural design involving a small number of complex logic gates. Circuit design of complex adiabatic gates, based on ordered binary decision diagrams (OBDD), is introduced. An optimized architecture for adiabatic parallel multipliers is proposed and savings in energy dissipation over competing architectures are estimated. Experimental results obtained from implementation of an adiabatic multiply-accumulate (MAC) unit suggest that the proposed strategy provides substantial improvement in energy efficiency over equivalent non-adiabatic and alternative adiabatic implementations, while achieving a competitive operating speed. 相似文献

This brief proposes a novel low-power digital logic design scheme based on the energy exchange in the switched inductor-capacitor (SLC) circuit. It presents a design paradigm which in ideal case may lead to a circuit capable of performing logic operations with no switching losses. In traditional integrated circuit design, the energy is stored in the output load capacitor through a pull-up path (corresponding to storing a logic 1). When the output changes its logic value, this stored energy is dissipated through the pull down path to the ground. In order to reduce this switching energy dissipation each time the load capacitor is discharged, we store its energy in the magnetic field of the inductor in the proposed SLC architecture. Whenever the output load needs to be charged again, we transfer the energy back from the inductor to the load capacitor. This significantly reduces the switching energy. We illustrated the operation of the SLC architecture through SPICE simulation. A brief discussion of some practical considerations for this architecture is also presented 相似文献

Adiabatic dynamic logic 总被引:2,自引:0,他引:2
With adiabatic techniques for capacitor charging, theory suggests that it should be possible to build gates with arbitrarily small energy dissipation. In practice, the complexity of adiabatic approaches has made them impractical. We describe a new CMOS logic family-adiabatic dynamic logic (ADL)-that is the result of combining adiabatic theory with conventional CMOS dynamic logic. ADL gates are simple, general, readily cascadable, and may be fabricated in a standard CMOS process. A chain of 1000 ADL inverters has been constructed in 0.9 μm CMOS and successfully tested at 250 MHz. This result, together with comprehensive circuit simulation, suggest that ADL offers an order of magnitude reduction in power consumption over conventional CMOS circuitry 相似文献
