Recently, several power estimation techniques have been proposed. Some of them can be used to accurately estimate power dissipation provided that the exact signal probability (probability of a signal being logic ONE) and signal activity (probability of signal switching) of primary inputs are known. In general, very accurate speciication of primary input signal probability and activity may not b...

Power dissipation is an increasing concern in VLSI circuits. New logic circuits have been developed to meet these power requirements. Power dissipation can be minimized by using various adiabatic logic circuits.

In the history, the major issues of the VLSI designer were area, cost, performance, and reliability; power concern was typically of only lesser importance. But more than the last few years’ power in the circuit is the major difficulty at the present days which is being faced by the very large scale integration industries. The power dissipation in several circuits is typically take place by the ...

In recent years, circuit size has increased due to scaling down of technology. Controlling power dissipation in these large circuits during test sessions is one of the major concerns in VLSI testing. In general power dissipation of a system in test mode is higher than the normal mode. This extra power can cause problems such as instantaneous power surge that causes circuit damage, formation of ...

Ramped-step voltage supplies are widely used in adiabatic switching. However, the set of analytical parameters available for understanding these voltage supplies is still limited. Our objective is to identify the parameters that have an effect on lowering power dissipation. Our results show that power dissipation can be significantly reduced using adiabatic logic, by increasing the charging and...

Power optimization is one of the important challenges in VLSI circuit for testing engineers. Larger power dissipation becomes the reason for overheating and with every increase in 10oC in operating temperature, failure rates for the component on a chip doubles. Power dissipation is directly proportional to switching activities of the components on Integrated Circuits. Power optimization is poss...

With technology scaling, growing wire delays and excess power dissipation of current metallic interconnects are predicted to significantly limit the performance of Networkon-Chips (NoCs) architectures. Recent research has focused on developing alternate solutions to current metallic interconnects. One potential solution is silicon photonics because of its higher bandwidth, reduced power dissipa...

DSP-based chromatic dispersion compensation accounts for a large part of the overall power dissipation in fiber-optic receiver ASICs.
