The performance of existing adders varies widely in their speed and area requirements, which in turn sometimes makes designers pay a high cost in area especially when the delay requirements exceeds the fastest speed of a specific adder, no matter how small the difference is. To expand the design space and manage delay/area tradeoffs, we propose new adder architecture and a design methodology. T...

This paper presents a new method to compensate the nonlinearity for matrix converter drives using disturbance observer. The nonlinearity of matrix converter drives such as commutation delay, turn-on and turn-off time of switching device, and on-state switching device voltage drop is modeled by disturbance observer and compensated. The proposed method does not need any additional hardware and of...

This paper addresses the problem of acoustic source localization in shallow water environment commonly dominated by impulsive noise and multipath phenomenon. Traditionally acoustic source localization with sensors spaced several wavelengths apart involves Time Delay Estimation (TDE) via Generalized Cross-Correlation Phase Transform (GCCPHAT). However multipath signals and impulsive noise in und...

Power consumption and delay are two of the most important constraints in current-day on-chip bus design. The two major sources of dynamic power dissipation on a bus are the self capacitance and the coupling capacitance. As technology scales, the interconnect resistance increases due to shrinking wire-width. At the same time, spacing between the interconnects decreases resulting in an increase i...

At-speed scan testing has become necessary to detect the growing population of timing defects in today’s nanometer-scale process. There are several at-speed delay test methods available in the industry to generate the delay patterns. Manufactures are continuing to look for ways to improve the effectiveness of at-speed delay test. The key is to create high quality, cost effective tests for these...

Barn owls localize a stationary auditory target with high accuracy. They might also be able to hit a target that is intermittently moving while the owl is approaching. If so, there should be a critical delay before strike initiation, up to which the owl can adapt its flight path to a new stimulus position. In this study, this critical stimulus delay was determined in a three-dimensional free-fl...
