As MOSFET sizes and wire widths become very small in recent years, in uence of resistive component of interconnects on the estimation of propagation delay and power dissipation can no longer be neglected. In this paper we present formulas of output waveform at driving point and short-circuit power dissipation for static CMOS logic gates driving a CRC load. By representing the short-circuit curr...

Power dissipation has become one of the major concerns of VLSI circuit design with the rapid launching of battery operated applications. In high performance designs, the leakage component of power consumption is comparable to the switching component. This percentage will increase with technology scaling unless effective techniques are introduced to bring leakage under control. In this paper, a ...

ABSTRACT: Power consumption has become a critical concern in both high performance and portable applications. Methods for power reduction based on the application of adiabatic techniques to CMOS circuits have recently come under renewed investigation. In thermodynamics, an adiabatic energy transfer through a dissipative medium is one in which losses are made arbitrarily small by causing the tra...

As the density and operating speed of complementary metal oxide semiconductor (CMOS) circuits increases, dynamic power dissipation has become a concern in the design of VLSI circuits. This paper presents a Two-Phase Adiabatic Static Clocked Logic (2PASCL) which shows the lowest power dissipation among different adiabatic logic families based on energy recovery principle. In adiabatic switching ...

Bit swapping linear feedback shift register (BS-LFSR) is employed in a conventional linear feedback shirt register (LFSR) to reduce its power dissipation and enhance its performance. In this paper, an enhanced BS-LFSR for low power application is proposed. To achieve low power dissipation, the proposed BS-LFSR introduced the stacking technique to reduce leakage current. In addition, three diffe...

Dynamic branch predictor logic alone accounts for approximately 10% of total processor power dissipation. Recent research indicates that the power cost of a large dynamic branch predictor is offset by the power savings created by its increased accuracy. We describe a method of reducing dynamic predictor power dissipation without degrading prediction accuracy by using a combination of local dela...

Abstract: In this paper, a power-gating technology for single-rail MOS Current Mode Logic (SRMCML) circuits is presented, which use the high-threshold PMOS transistors as linear load resistors to reduce the power dissipation in the sleep mode. The basic SRMCML cells, such as buffer/inverter, AND2/NAND2, AND3/NAND3, OR2/NOR2, OR3/NOR3, XOR2/XNOR2, multiplexer, and 1-bit full adder, are used to v...

This paper deals with the design opportunities of Static Random Access Memory (SRAM) for lower power consumption and propagation delay. Initially the existing SRAM architectures are investigated, and thereafter a suitable basic 6T SRAM structure is chosen. The key to low power dissipation in the SRAM data path is to reduce the signal swings on the highly capacitive nodes like the bit and data l...

The SRAM (static random access memory) extensively used in computers, embedding hardware, and other digital systems is a main source of power dissipations. In order to reduce the increasing power dissipation of the SRAM, a low-power adiabatic SRAM is introduced. The proposed SRAM is realized by PAL-2N (pass-transistor adiabatic logic with NMOS pull-down configuration) to reduce its dynamic ener...

Now a day’s technology enhancement is at a blistering pace. Merely VLSI has a meteoric rise due to the adoption of new techniques. Static CMOS had a limitation of deploying constant power supply. Less power dissipation is an essential attribute for any optimized design. Varying the power supply is the very thing for preventing the power dissipation. An adiabatic logic is a new technique to redu...
