Title: Conversing with the Brain
Speaker: Prof. Karim G. Oweiss, Michigan State University
Abstract: Brain machine interfaces (BMIs) are a direct communication pathway between the brain and a man-made device, with an ultimate goal of improving the lifestyle of neurologically impaired subjects. For these systems to operate optimally, some means of bi-directional translation should occur between the signals that the brain uses for its internal communication and those used by the machine to achieve a desired functional outcome. In this talk, I will discuss some of our recent efforts to establish a readout methodology that translates neural ensemble activity to machine language. I will follow with a brief discussion on how to optimize microstimulation of these ensembles to increase the effectiveness of BMIs. I will conclude with a brief overview of our progress in engineering a wireless, fully implantable system for large-scale neural interfaces to pave the way for deploying BMIs in clinical applications.

Title:From Implantable Microelectronic Devices to Modern Assistive Technologies
Speaker: Prof. Maysam Ghovanloo who is at Georgia Institute of Technology
Abstract: In this talk, I will give an overview of the recent progress in GT-Bionics Lab. The applications of implantable microelectronic devices (IMD) are on the rise, because advancements in microelectronics, RF communications, and medicine have resulted in adding more functionality in IMDs that occupy smaller space and run on lower power levels to address more complex diseases and disabilities. I will address how we are pushing the limits on developing basic building blocks for such state-of-the-art IMDs, particularly on the analog front end, RF backend, and power management units. One of many applications of IMDs is brain-computer interfacing (BCI), which is meant to enable individuals with severe physical disabilities to control their environments, particularly by accessing computers and driving powered wheelchairs. Implantable BCIs are highly invasive and despite all the investments, it is not clear whether end users would accept them in the presence of much less invasive alternatives. Therefore, in GT-Bionics Lab we pursue BCIs as advanced tools for neuroscience research applications on small animal subject. At the same time, we are exploring novel minimally invasive methods for individuals with severe paralysis to make the best use of their remaining abilities to control their environments. An example of this is a brain-tongue computer interface (BTCI), called the Tongue Drive System, which will be covered.

Title: RF/DSP Co-Designed Power amplifiers for Software Defined Radio Systems
Speaker: Prof. Fadhel Ghannouchi, University of Calgary
Location: EEB 248
Date: Friday, October 14, 2011
Time: 3pm – 4pm
Abstract:
The next wave in the information revolution will consist of bringing intelligence to the information and communication technology (ICT) sector, allowing seamless and intelligent networking and communication between different users using different services and operators. This will lead to the convergence of communication technologies, aiming at the development and deployment of cooperative and ubiquitous networks that involve existing and future wireless and satellite communications systems.
A critical element in enabling the convergence of different communication systems is the development of software defined radio (SDR) systems that can be used across different frequency bands and for multi-standard applications. This SDR has to be developed to support different frequency carriers and modulations schemes concurrently, in addition to being power and spectrum-efficient, in order to be able handle high data rates, while being less energy hungry and more environmentally friendly.
The design of power amplifiers as critical components in any SRD based communication terminal has to be considered closely together with the system architecture, in order to ensure optimal system level performances in terms of linearity and power efficiency. This implies the use of adequate transmitter architectures that convert the analog baseband information to architecture dependent amplifier driving signals, such as sigma-delta, EE&R, Polar and LINC architectures. This talk lays out the principles behind SDR systems and examines the design of software-enabled linear and highly efficient RF/DSP co-designed power amplifiers/transmitters for multi-standard and multi-band applications. Recent advances and practical realizations will also be presented and discussed.

Title: Multi-Gbps Optical Receivers with CMOS Integrated Photodetectors
Abstract: The integration of high-speed optoelectronics alongside CMOS garners much research attention. Consider how the emergence of CMOS image sensors in the 90's revolutionized and proliferated digital cameras. Likewise, a multi-Gb/s CMOS photodetector enables highly-integrated, compact, and low cost optical receivers opening up new applications for optical links in data centers, consumer electronics, and automobiles.
As photodiodes, the pn-junctions and depletion regions available in a standard CMOS process have an intrinsic bandwidth of, at most, 10’s of MHz, so considerable innovation has been required to make them useful for multi-Gb/s communication. “CMOS photonics” researchers seek modifications to standard CMOS processing that will permit the integration of high-performance photodetectors and optical waveguides, for example made of germanium. By contrast, this presentation illustrates that the slowly diffusing photocarriers that usually limit the bandwidth of photodetectors made in standard CMOS may be considered simply a form of ISI. Hence, the bandwidth limitations of such CMOS photodetectors can be dealt with using the same signal processing tools being applied with success in other wireline communication applications. A combination of spatially-modulated light detection, analog equalization, and modest decision feedback equalization appears to offer a path towards data rates in excess of 10-Gbps using standard CMOS photodetectors. Nanoscale CMOS is particularly well suited to the implementation of such signal processing functions, and prototype results ranging from 0.18um CMOS to 65nm CMOS will be presented.

Title: Prospects of Semiconductor on Insulator (SOI) Technology in Power Amplifiers and Integrated Nanoelectromechanical Systems
Abstract: Silicon on Insulator (SOI) technology has been widely used for low power analog and digital circuits for applications in mobile computation and communication. An addition of a buried oxide layer beneath a thin Si device layer in SOI technology brings about a new physics to the CMOS transistor, one that is still not fully understood. The buried oxide layer reduces the parasitic capacitance of interconnect metallization and transistors to the Si substrate which in turn reduces the dynamic power dissipation. Moreover, the buried oxide layer, when combined with trench oxide, helps electrically isolate CMOS transistors from each other and from the Si substrate. Electrically isolated SOI transistors can be stacked on top of each other to form power amplifiers with large voltage swing signals at the output. On the other hand, buried oxide layer facilitates micromachining of thin Silicon Nanowires that can be easily made into suspended double-clamped nanoelectromechanical resonators. In this presentation, SOI applications in both power amplifiers and integrated nanoelectromechanical systems are revisited and our most recent results are presented.
Biography: Saeed Mohammadi graduated with a Masters degree in Electrical Engineering from the University of Waterloo, ONT, Canada in 1994. He earned his PhD degree in Electrical Engineering from the University of Michigan in Ann Arbor in 2000. Since 2002, he has been at Purdue University where he currently serves as an Associate Professor. His research interests are in the areas of experimental nanotechnology and RF circuits. Together with his students, Prof Mohammadi has published more than 120 papers in these areas including the first carbon nanotube RF transistor, the first transparent flexible display technology based on carbon nanotube thin film transistors and the first RF CMOS receiver implemented in subthreshold regime.More Information: 10.28.11 Seminar_Speaker_Mohammadi.pdf
