Two high performance level restoration circuits are proposed, which outperform the existing level restoration circuits with cross-coupled PMOS, in terms of power dissipation and delay. The first configuration employs a back-bias scheme in order to eliminate the stand-by leakage caused by the low-swing input. The second one adopts a bootstrapping technique, in order to restore the low swing sign...

The dynamic model of a power system is the combination of the power flow equations and the dynamic description of the generators (the swing equations) resulting in a differential-algebraic equation (DAE). For general DAEs solvability is not guaranteed in general, in the linear case the coefficient matrices have to satisfy a certain regularity condition. We derive a solvability characterization ...

of the Thesis Design and Analysis of Custom Clock Buffers and a D Flip-Flop for Low Swing Clock Distribution Networks by Mallika Rathore Master of Science in Electrical Engineering Stony Brook University 2014 With higher integration, power has become a primary concern for IC design. Clock signal has the highest switching activity and can be responsible for up to 40% of the overall power dissipa...

Problem statement: The inter-area power systems have special characteristic of the stability behavior. The improvement of inter-area power system is one of the important aspects in power system. Approach: This study applies the Static Synchronous Series Compensator (SSSC) to improve stability of inter-area systems. The SSSC is modeled and then is applied to be incorporated into the power system...

In walking, humans prefer a moderate step width that minimizes energetic cost and vary step width from step-to-step to maintain lateral balance. Arm swing also reduces energetic cost and improves lateral balance. In running, humans prefer a narrow step width that may present a challenge for maintaining lateral balance. However, arm swing in running may improve lateral balance and help reduce en...

Measurements are presented of the speed at which six different rods could be swung by four male students. Three of the rods had the same mass but their swing-weight (i.e. moment of inertia) differed by large factors. The other three rods had the same swing-weight but different masses. Our primary objective was to quantify the effects of mass and swing-weight on swing speed. The result has a dir...

We describe a structure of model for shortterm swing dynamics of multi-machine power grids, exhibiting an instability phenomenon termed the Coherent Swing Stability (CSI). This model is based on the swing equations with a linear term representing the interconnection between synchronous machines in a power grid. We analyze the New England 39-bus test system exhibiting CSI and show that the pheno...

This paper proposes a novel anti-swing control strategy for an overhead crane. The controller includes both position regulation and anti-swing control. Since the crane model is not exactly known, fuzzy rules are used to compensate friction, gravity as well as the coupling between position and anti-swing control. A high-gain observer is introduced to estimate the joint velocities to realize PD c...

For the use of green energy and ubiquitous computing, this study investigates miniature electric generators that are constructed with piezoelectric benders. Electric power is generated by vibratory deformation of piezoelectric benders. Three different designs of piezoelectric generators are created and compared in this study by using mechanics analysis. The result shows that the cantilever desi...
