| To accurately estimate power dissipation, the exact signal probability (probability of a signal being logic ONE) and signal activity (probability of signal switching) of primary inputs are assumed to be known. In general, very accurate speciication of primary input signal probability and activity may not be available. This in turn may result in uncertainties in average power estimation. In th...

background and objective: in magnetic fluid hyperthermia therapy, controlling temperature elevation and optimizing heat generation is an immense challenge in practice. the resultant heating configuration by magnetic fluid in the tumor is closely related to the dispersion of particles, frequency and intensity of magnetic field, and biological tissue properties. methods: in this study, to solve h...

This paper explores the role of branch predictor organization in power/energy/performance tradeoffs for processor design. We find that as a general rule, to reduce overall energy consumption in the processor it is worthwhile to spend more power in the branch predictor if this results in more accurate predictions that improve running time. Two techniques, however, provide substantial reductions ...

Low Power Design is a critical concern and metric for today's complex designs. During scan based manufacturing test, power dissipation becomes even more critical as the chip may not have been designed to tolerate excessive switching during scan test. Excessive power dissipation during scan test can result in excessive voltage variations, reduced noise margins and other signal integrity issues w...

Continuous-wave Raman amplification in silicon waveguides with negative electrical power dissipation is reported. It is shown that a p-n junction can simultaneously achieve carrier sweep-out leading to net continuous-wave gain, and electrical power generation. The approach is also applicable to silicon Raman lasers and other third-order nonlinear optical devices. 1 Silicon-on-Insulator (SOI) ha...

The main goal of this paper is to provide new low power solutions for very large scale integration. Designers especially focus on the reduction of the power dissipation which shows increasing growth with the scaling down of the technologies. In this paper various technologies at the different levels of the design process have been implemented to reduce the power dissipation at the circuit, arch...

In this paper a CMOS operational amplifier is presented which operates at 2V power supply and 1uA input bias current at 0.8 um technology using non conventional mode of operation of MOS transistors and whose input is depended on bias current. The unique behaviour of the MOS transistors in subthreshold region not only allows a designer to work at low input bias current but also at low voltage. W...

Rapid increases in chip complexity, increasingly faster clocks and proliferation of portable devices have combined to make power dissipation an important design parameter. The power consumption of a system determines its heat dissipation as well as battery life. For some digital systems, power consumption has become the most critical design constraint. To satisfy the low power requirement one o...
