AC and Stability Analysis in NGSPICE

The above example shows an AC analysis test-bench GSCHEM. In this example the loop is broken by R3 whose value at dc is 1mO and is changed to 1TO for ac analysis. Doing this enables NGSPICE to converge on a sensible dc operating point for open loop analysis without any imperfections such as input offset forcing the output to one of the supply rails.

Wearable Sensing and Computing

 Wearable Sensing and Computing 
 05.11.2014 - 06.11.2014
 EPFL Lausanne (CH)

The course main objective is to inform and discuss in great details the latest advancements in low power sensing technology, energy harvesting and their heterogeneous integration for wearable smart system applications. Technological roadmaps of performance and future evolutions will be presented. The low power wireless communications are discussed from the point of view of existing standards and challenges for reducing the energy per communicated bit. Another objective is to detail some key future applications for wearable sensing and computing with main emphasis on: (1) medical Diagnostics, monitoring and prevention and (2) sports, fitness and activity monitoring applications. We analyze the benefits of autonomous smart system technology from many different points of view, including that of the individual, the physician, health care management, and society in general. We provide a rationale on the role of such technology as a component of the care cycle and the changes it can induce by reinforcing preventive strategies.

Dr. Jindal has been nominated for the Delegate-Elect/Director-Elect 2015

Dr. Renuka Jindal is Professor of Electrical and Computer Engineering at the University of Louisiana at Lafayette, LA, USA since 2002. His research and teaching interests lie in the theory and practice of random processes applicable to a wide variety of phenomena in electronic and photonic devices and circuits, lightwave and wireless communications systems and biological organs. Dr. Jindal was elected Fellow of IEEE in 1991 for his seminal work reducing MOSFET noise by almost an order of magnitude for analog and RF applications. He is also a recipient of the IEEE 3rd Millennium medal. For last four decades of his dual career in industry and academia, Dr. Jindal rose through the ranks as Editor, Editor-in-Chief, VP of Publications, and as EDS President in 2010- 2011. As President he formulated the vision and mission of EDS enhancing member benefits launching a plethora of initiatives reversing the decline in EDS membership. A partial list of his accomplishments is given below:

As Senior-Past President of EDS Dr. Jindal is still very much engaged with IEEE. Recently, Dr. Jindal has been nominated by IEEE Division I to run for the Delegate-Elect/Director-Elect 2015 position in the upcoming IEEE elections. The electorate consists of members of three societies i.e. Electron Devices (ED), Solid-State Circuits (SSC) and Circuits and Systems (CAS). The slate consists of three candidates one from each of these societies. 

On his behalf, I suggest to contact your colleagues in IEEE regions 1-10 for his support since IEEE ballots will be out by August 15.
