The performance of a circuit depends on its clock period. The shorter a valid clock period is, the better the performance is. The clock period is tightly related to the diierence between the longest propagation delay and the shortest propagation delay from primary inputs to primary outputs. The objective of this paper is to minimize the amount of delay inserted while achieving the shortest cloc...

Repeat-pass synthetic aperture radar interferometry is an important tool for measuring earth surface topography and/or surface deformations. These observations, however, are highly affected by the atmosphere. Therefore, an accurate description of atmospheric distortions is very important to improve an accuracy of interferometric measurements. In this paper we discuss influence of hydrometeors o...

This paper presents a comparative analysis of reduced segment; T and ? RLC interconnect models. With down scaling of technology, the interconnect structures have became a predominant factor in determining the overall circuit performance. Controlling interconnect propagation delay is the fundamental parameter to high speed VLSI designs. In this work, model performance has been evaluated in terms...

This paper addresses the issues of power dissipation and propagation delay in CMOS buffers driving large capacitive loads and proposes a CMOS buffer design for improving power dissipation at optimized propagation delay. The reduction in power dissipation is achieved by minimizing short circuit power and subthreshold leakage power which is predominant when supply voltage (VDD) and threshold volt...

The analysis of Magneto Inductive communication technique due to underwater communication having multipath fading, dynamic channel and high propagation delay . The performance studies of 3D network covering 100 of meter of sea depth and few km square area show fully connected multi coil network with communication bandwidth extending from few to tens of kHz. The low speed of sound in water, diff...
