We propose a novel substrate-bias control scheme for an FD-SOI SRAM that suppresses inter-die variability. The proposed circuits detect inter-die threshold-voltage variation automatically, and then maximize read/write margins of memory cells to supply the substrate bias. We confirmed that a 486-kb 6T SRAM operates at 0.42 V, in which an FS corner can be compared as much as 0.14 V or more. key w...

A highly-efficient, flexible piezoelectric PZT thin film nanogenerator is demonstrated using a laser lift-off (LLO) process. The PZT thin film nanogenerator harvests the highest output performance of ∼200 V and ∼150 μA·cm(-2) from regular bending motions. Furthermore, power sources generated from a PZT thin film nanogenerator, driven by slight human finger bending motions, successfully operate ...

Die vorliegende Arbeit befasst sich mit der Konzeption eines agentenbasierten Systems zur Lösung komplexer Fragestellungen aus dem Bereich der Transportlogistik. Hierzu wird die generelle Klasse der Tourenplanungsprobleme betrachtet. Das vorgestellte Konzept bietet dem Anwender die Möglichkeit, eine Vielzahl verschiedener problemspezifischer Charakteristika zu berücksichtigen, welche sich beisp...

Dependence of within-die delay variations on power supply voltage (VDD) is measured down to 0.4 V. The VDD dependence of the within-die delay variation of manual layout and irregular auto place and route (P&R) layout are compared for the first time. The measured relative delay (=sigma/average) variation difference between the manual layout and the P&R layout decreases from 1.56% to 0.07% with r...

B dem Versuch, quantitative Aussagen über die von Atomkernen ausgehenden Strahlungen zu machen, bildet die Absolutmessung von yStrahlen ein besonderes Problem, weil die Empfindlichkeit der Nachweisinstrumente für y-Strahlen schwer zu bestimmen ist. Für die Messung der ^-Empfindlichkeit von Zählrohren hat sich die Koinzidenzmethode in der zuerst von W. B o t h e und H. J. v o n B a e y e r 2 ang...

This paper presents the implementation of power fluctuation compensation for an intensity-based optical fibre bending sensor aimed at monitoring human spine bending in a clinical environment. To compensate for the light intensity changes from the sensor light source, a reference signal was provided via the light reflection from an aluminum foil surface fixed at a certain distance from the sourc...

Springback and longitudinal bow are two major shape defects in gradual forming processes like chain-die roll forming. In this study, the springback of AHSS hat U profiles investigated through experiment finite element simulation. The disparity along direction signifies complex deformation during Based on simulation forming, process realized by sequential die blocks causes bending reverse-bendin...
