utah.eduMassive data movement is a key requirement in modern multi-core multi-processor computing machines. Due to heat, yield, and performance concerns, many high-end products are now moving toward Multi-Chip-Module (MCM) SoC architecture. In such systems, the data rate as well as energy consumption are extremely crucial. Thus, new design methodologies and communication schemes are required to implement high-throughput and energy-efficient links. Advanced Multi-Input Multi-Output signaling schemes will be introduced in this seminar that can enhance the total communication bandwidth over short- and long-reach copper channels. Novel circuit architectures in conjunction with low-ISI (Inter-Symbol-Interference) sensitivity signaling method allows to implement very energy-efficient and very high-speed links. Examples will be provided to evaluate performance of the proposed serial data transceiver.

| تاریخ ارسال: 1400/8/17 |
Abstract:
There are plenty of intriguing physical phenomena around us: from wave propagation in ocean to the movement of roller-coasters. These everyday examples can be used as inspiration in analog and RF circuit design. In this talk, we will show three examples of novel circuits that can achieve a much better performance compared to the conventional circuit topologies. The examples are focused on high speed, broadband, and low noise circuits.

سخنرانی دکتر Sudip Shekhar با عنوان Silicon: The playground for photons and electrons
| تاریخ ارسال: 1400/8/23 |
Silicon: The playground for photons and electrons
The devices in the arsenal of a CMOS designer include resistors, capacitors, inductors, and transistors. What happens when we add light to that? With an ability to move the information between electrons and photons, many new opportunities and applications will emerge. In the last five years, silicon photonics - where light is guided in a silicon waveguide on a CMOS SOI process, has already had a significant impact in the field of high-speed transceivers for data communications.
Which applications will become mainstream in the next ۵-۱۰ years? Sensing? Computing? RF & Microwave? Quantum? What will be next in communications?
And how can we easily add photonics to the arsenal of the CMOS designer and make its adoption seamless? I will attempt to answer some of these questions in this talk. I will also highlight the opportunities that lie ahead for a CMOS designer in adopting this technology - now ready to be deployed.
Sudip Shekhar received his B.Tech. degree from the Indian Institute of Technology, Kharagpur, and the Ph.D. degree from the University of Washington, Seattle. From ۲۰۰۸ to ۲۰۱۳, he was with the Circuits Research Laboratory, Intel Corporation, Hillsboro, OR, USA, where he worked on high-speed I/O architectures. He is now an Associate Professor of Electrical and Computer Engineering with The University of British Columbia, Vancouver.

سخنرانی دکتر امید مومنی:Scalable Standing Wave Integrated Circuits for Reconfigurable Power Generation, Radiation and Beam Steering at mm-Wave and Terahertz Spectrum
| تاریخ ارسال: 1400/8/28 |
Scalable Standing Wave Integrated Circuits for Reconfigurable Power Generation, Radiation and Beam Steering at mm-Wave and Terahertz Spectrum
Abstract
The power generation of transistors drops as we move to higher frequencies. At the same time, the free space propagation loss increases, demanding more radiated power from the system. The loss of passive elements in the circuit increases as well, making functions such as oscillation or radiation even more challenging. In order to boost the limited power, multiple sources need to be coupled together in an array structure. However, the significant loss of the coupling circuitry and phase shifters at mm-wave and terahertz frequencies hinders the implementation of large and efficient radiator and phased arrays. Scalable standing wave array structures are proposed based on efficient low-loss coupling schemes in order to boost the power and operation bandwidth. Furthermore, we present a practical approach to maximize Equivalent Isotropic Radiated Power (EIRP) of the source by optimizing influential parameters of the radiation apparatus. Finally, we demonstrate a new phase shifting method based on combining standing and traveling waves and show how it can achieve significantly higher reconfigurability, phase shifting range and bandwidth. Using all these methods we present coupled-oscillators, scalable radiator arrays, and reconfigurable phased arrays with record beam steering range, tuning range, and output power at mm-wave and terahertz frequencies.

سخنرانی دکتر پرویزی: high-speed clock generation and distribution for data converters
| تاریخ ارسال: 1400/9/16 |
Abstract: High-speed serial and optical I/Os are driven continuously to higher density and bandwidth to enable the scaling of data centers to meet the demand imposed by a digitally connected world. The DSP based wireline and optical transceivers rely on high baud-rate data converters to transmit and receive the data. These data converters rely on high frequency, low jitter clocks to sample the data. This talk covers the requirements of a high-speed clock generation and distribution for data converters used in high-speed serial and optical I/Os and the latest design techniques to generate them with low power consumption to meet the stringent requirements of data-center interconnect.

سخنرانی دکتر شعاعی با عنوان: Neural Electrical Stimulation Electronics
| تاریخ ارسال: 1400/9/28 |
Title: Neural Electrical Stimulation Electronics
13-14:30 Saturday 26 Dec. 2021
Abstract: Implantable neural electrical stimulators can be used to treat a variety of neurological disorders and/or restore some body functions such as DBS (Deep Brain Stimulation) for Parkinson disease, SCS (Spinal Cord Stimulation) for chronic pain, Cochlear Implants for stimulating cochlear nerves for inner hearing loss, Epiretinal prosthesis for treating retinal degenerative diseases, etc.
The power efficiency and safety of the electrical stimulators are uncompromisable. Also, the characteristics of the stimulator such as the voltage compliance, and current/voltage resolution are among the design challenges defining the ASIC technology node. Some charge balancer circuits and systems to ensure the electrical stimulation safe for both the tissue and the electrode are presented. Multi-channel concurrent stimulation and generating different waveforms to increase the efficacy are also discussed. Different types of neural stimulation circuitries are introduced, and as an example, an energy efficient multichannel adiabatic switching-based stimulator with high driving current capability (up to 10 mA) is presented in more details. The stored energy in the electrode-tissue capacitor in the first phase of the stimulation will be mostly recovered in the second phase. The proposed stimulator consists of a dynamic differential power supply which makes the biphasic stimulation possible without the need of H-bridge.
Omid Shoaei (M'96) received the B.Sc. and M.Sc. degrees from University of Tehran, Iran, in 1986 and 1989, respectively, and the Ph.D. degree fromCarleton University, Ottawa, Ont., Canada, in 1996, all in Electrical Engineering.
