Employing Dynamic Body-Bias for Short Circuit Power Reduction in SRAMs

Dynamic body-biasing is a well studied approach for reducing the leakage power in memory systems. Proposed designs dynamically change the body bias of the inactive memory cells in order to tune their threshold voltages. However, prior body biasing schemes only focus on the static power reduction and overlook the power dissipation stemmed from the short circuit current. Recent studies showed that the neglected short circuit power became significant fraction of the overall power consumption in CMOS circuits. On the other hand, conventional short circuit power optimization techniques are not appropriate for the memory cells due to the area and performance constraints. In this study, we propose a supplementary body biasing scheme to address the short circuit current issue of the SRAM cells. We contend that the technique can easily be adapted to many former body-bias schemes and enables significant short circuit current reduction with slight performance impact.

Advanced Active Power Filter to Improve Power Quality
Gurguiatu, Gelu; Balanuta, Ciprian; Rosu, Emil; Munteanu, Toader; Dumitrescu, Mariana; Raducan, Elena (2011-09-10)
This paper presents a three-phase Active Power Filter (APF) to improve grid power quality. Starting from indirect control strategy which was used only for three legs - three wires it is proposed in this paper to be used a bridge with three legs - four wire. The new control strategy it was named extended indirect control strategy. The extension consists in passing from the control of a three wire active power filter to the control of a four wire active power filter. The proposed active power filter can compe...
An Efficient Parallel Solution Framework for the Linear Solution of Large Systems on PC Clusters
Kurç, Özgür (Tsinghua University Press, 2008-10-01)
In this paper, a parallel solution framework for the linear static analysis of large structures on PC clusters is presented. The framework consists of two main steps: data preparation and parallel solution. The parallel solution is performed by a substructure based method with direct solvers. The aim of the data preparation step is to create the best possible substructures so that the parallel solution time is minimized. An actual structural model was solved utilizing both homogeneous and heterogeneous PC c...
Composite index for benchmarking local energy systems of Mediterranean port cities
Kılkış, Şiir (2015-12-01)
Benchmarking the performance of local energy systems requires an integrated approach. This paper develops a composite index that consists of a unique set of 7 dimensions and 35 main indicators. The SDEWES (Sustainable Development of Energy, Water, and Environment Systems) Index is applied to a sample of 22 Mediterranean port cities. The index integrates energy and CO2 emissions data from SEAP (Sustainable Energy Action Plans). The values of the indicators are aggregated based on the Min-Max method for a fin...
Real-Time Detection of Interharmonics and Harmonics of AC Electric Arc Furnaces on GPU Framework
Uz-Logoglu, Eda; Salor, Ozgul; Ermiş, Muammer (2019-11-01)
In this paper, a method based on the multiple synchronous reference frame analysis is recommended and implemented to detect time-varying harmonics and interharmonics of rapidly fluctuating asymmetrical industrial loads. The experimental work has been carried out on a typical three-phase alternating current arc furnace installation. In the recommended method, the reference frame is rotated in both directions at speeds corresponding to the positive and negative sequences of all harmonics and all interharmonic...
