Dr Zidan aims high

posted Jul 16, 2018, 7:46 PM by Khaled salama

Our first PhD graduate, Dr Mohamed Zidan, continues to demonstrate a high calibre work during his postdoctoral fellowship. Check his recent nature publications below.  Zidan did his PhD on Memristor circuits and systems. Throughout his PhD he published a record 10 journal and 14 conference papers. Details can be found here.  Its worth mentioning that Zidan was awarded the prestigious IEEE circuits and systems society pre-doctroal scholarship in 2014 and was invited to the very selective 65th Lindau Nobel Laureate Meeting in 2015. His work on "Memristor-based memory: The sneak paths problem and solutionsat the microelectronics journal is the most cited and appears on the top 25 hottest papers for 2014.  We are proud of Zidan and we wish him good luck with his academic job search.

Late Breaking news:A Low-Power Time-Domain Comparator for IoT Applications

posted Jul 8, 2018, 4:15 PM by Khaled salama   [ updated Jul 8, 2018, 4:21 PM ]

We just got a paper accepted at the 61st IEEE International Midwest Symposium on Circuits and Systems (MWSCAS) at the Late Breaking news session titled A Low-Power Time-Domain Comparator for IoT Applications",  This paper introduces a low-power time-domain comparator with a modified current starved inverter circuit. The proposed comparator converts the analog input voltage into a time delay that creates a phase difference between the input signal and the reference signal offering a FoM of 60 fJ/conversion step. Finally, the proposed time-domain comparator circuit is compatible with wide range of applications (i.e., internet of things (IoT) sensors and integrated DC-DC converters). 

Special issue on Large-scale Memristive Systems and Neurochips for Computational Intelligence

posted Jul 8, 2018, 11:26 AM by Khaled salama

Stay tuned for the publication of our special issue on  Large-scale Memristive Systems and Neurochips for Computational Intelligence at The IEEE Transactions on Emerging Topics in Computational Intelligence. This special issue recognizes some of these grand challenges in this emerging field with a specific focus on modeling and simulations of memristors moving from smaller to a broader array of circuits, which can be further scaled to large-scale systems. In this special issue, papers reflecting different architectures and applications of memristors reflecting large-scale problems are presented. This special issue includes seven papers selected after a rigors peer-review process.  The topic of large-scale memristor circuits and systems for computational intelligence is an emerging topic and we hope that this issue provides an
advance towards taking the research a step higher in the right direction.

One final paper for Abdulaziz Alhoshany

posted May 20, 2018, 1:10 PM by Khaled salama   [ updated Jun 26, 2018, 9:57 PM ]

Abdulaziz, the most recent PhD graduate from our group, managed to get the last and final chapter of his thesis accepted at the prestigious 
IEEE Transactions on Instrumentation & Measurement.  In a paper titled, "A Precision, Energy-Efficient, Oversampling, Noise-Shaping Differential SAR Capacitance-to-Digital Converter ", we propose an energy-efficient, noise-shaping SAR CDC (NS-SAR CDC) for high precision that achieves capacitive resolution in the attofarad range. The proposed CDC architecture combines the merits of noise shaping and SAR CDC. High capacitive resolution is achieved by the introduced oversampling and noise shaping techniques in the SAR architecture. Large parasitic capacitance can be tolerated, and the differential implementation provides robustness against common mode noise, noise coupling, and errors. In addition, the proposed architecture overcomes the parasitic-dependent conversion errors which make the CDC robust and insensitive to parasitic capacitances.  The proposed differential noise-shaping SAR CDC achieves 150aF absolute resolution and an energy-efficiency FoM of 187fJ/conversion-step.

Congratulations Dr. Abdulaziz Alhoshany
