May 5, 2021. Congratulations to Rajath Bindiganavile for successfully passing his qualifying exam ! Good luck for the continuation of your studies. 

May 5, 2021. Congratulations to Asif Wahid for successfully passing his qualifying exam ! Good luck for the continuation of your studies. 

April 23, 2021. Armin Tajalli presented an invited talk in the IEEE Workshop on Microelectronics and Electronic Devices. The presentation was on Energy Efficient Multi-Wire Coding for Chip-to-Chip Communications. The lecture covers both signaling and modulation schemes, as well as circuit design approaches [Link].

April 30, 2021. Armin Tajalli will chair the Communication Circuits & Systems track in the IEEE MWSCAS’2021 conference (Lansing, Michigan) [Link].

April 24, 2021. A Armin Tajalli chairs the Advanced Optical and Electrical Communication Systems in IEEE CICC 2021. This session will include five excellent papers selected from both academia and industry. 

April 30, 2021. A team of 9 undergraduate Senior students accomplished their project in collaboration with LCAS. Tina Hayward, Ran Wei, Richard Christian, Sophie Wang, Israel Najar, Christian Giauque, Michael Dorman, Sun Geol Kim, and Ze-Hong Lin were part of this project in which a Successive-Approximation Analog-to-Digital Converter (ADC), a Pipelined ADC, a Current-Steering Digital-to-Analog Converter (DAC), and a Neural Network system for image recognition were designed. Congratulations to the team for their great achievement that included different activities, including modeling, circuit design, layout preparation, and simulation. Also, two team members, Tina Hayward and Sophie Wang, won the 2021 Electrical Engineering Student Excellence Award. Well deserved !

January 29, 2021. Congratulations to Asif Wahid and Rajath Bindiganavile for their recent paper accepted in IEEE ISCAS’2021. Entitled “Optimal PAM Order for Wireline Communication“, the main focus of this work is on analyzing and evaluating performance of high-order PAM signaling for wireline communications. This analysis shows how proper resolution for Analog-to-Digital Converters can be selected for wireline communications over a channel with strong Inter-Symbol Interference [Link].  

November 18, 2020. Our latest work on algorithmic/systematic analog design is now being published by IEEE TCAS-I. This article sheds light on energy-efficient analog circuit design from a new perspective. The main goal of this article is to provide a simple/analytical/systematic perspective on speed-power trade-offs in design of Field-Effect Transistors (FETs).  There are several approaches to implement energy-efficient analog circuits (e.g. gm/ID and inversion-coefficient based design). The proposed methodology in our latest paper offers a simpler and more insightful design approach.  

December 1, 2019. LCAS successfully accomplished development of an extremely high-throughput wireline link for next generation high-performance computing systems. Collaborating with industrial partner, the LCAS team developed new signaling schemes and circuit topologies in order to enhance the communication bandwidth at very low level of energy consumption. Targeting 100 Gb/s, this research work showed that energy consumption can be reduced down to 1.2 pJ/b for ultra-short reach channels. This type of channels are widely used in modern chip-to-chip communications. 

September 15, 2020. LCAS signs a collaboration contract with a leading company in Silicon Valley to develop high-speed integrated circuits for next-generation wireless 5G systems. This industrial fund will be used to develop, design, implement and test advanced integrated circuits, targeting high-throughput wireless communications.
