Very excited to announce that we will be presenting two papers at CICC2021! Proud of the hard work of our graduate students and collaborators! A great way to start in 2021!

1. Mansour Taghadosi and Hossein Kassiri, “An Analog Low-Power Highly-Accurate Link-Adaptive Energy Storage Efficiency Maximizer for Resonant CM Wireless Power Receivers”.

2. Fatemeh Eshaghi and Hossein Kassiri, “A 24-Channel Neurostimulator IC with One-Shot Impedance-Adaptive Channel-Specific Charge Balancing”.

Tania Moeinfard successfully defended her Master’s thesis. We are delighted that she has decided to continue her work in ICSL as a PhD student.

Thesis Title:

AN 8-CHANNEL BIDIRECTIONAL NEUROSTIMULATOR IC WITH A HIGHLY-LINEAR HIGH-DYNAMIC-RANGE ADC-DIRECT ARCHITECTURE FOR SIMULTANEOUS RECORDING AND STIMULATION

Congratulations Tania!

Al Freeman successfully defended his Master’s thesis. He will be working in Intel Toronto as an Analog IC Design Engineer!

Thesis Title:

WIRELESS IMPLANTABLE ICs FOR ENERGY-EFFICIENT LONG-TERM AMBULATORY EEG MONITORING

Congratulations Al!

ICSL has been awarded $250,000 by the Government of Canada under the New Frontiers in Research Fund (NFRF) – Exploration program to conduct research on “A Fully-Implantable mm-Scale Neuro-Stimulator for Temporally-Precise Single-Cell- Resolution Optogenetics”.

Four papers from ICSL members have been accepted for lecture presentation in IEEE EMBC 2020, Montreal, Canada. Congrats everyone!

• Kassiri, “Fully-Implantable Optogenetic Neuro-Stimulators: A Design Review and A mm-Scale Directivity-Enhanced Example SoC”, Accepted as part of a Minisymposia to 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), July 20-24, 2020, Montréal, Canada.
• Yousefi*, A. Dabbaghian*, H. Kassiri, “Motion Artifact in Non-Contact EEG Recording: Characterization and Analog Front-End Design”, Accepted as full paper to 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), July 20-24, 2020, Montréal, Canada.

One of our ISCAS’20 papers titled “A 3.12pJ/C Ultra-Low-Power Direct-ADC Multi-Range Temperature Sensor for IoT Nodes” by Tayebeh Yousefi & Hossein Kassiri has been selected as one of conference’s top accepted papers invited for a special issue of IEEE TCAS-II.

Our paper is accepted for oral presentation in IEEE Custom Integrated Circuits Conference (CICC) 2020 in Boston, USA.

T. Yousefi, M. Taghadosi, A. Dabbaghian, R. Siu, G. Grau, G. Zoidl, H. Kassiri, “A 12.5mg mm-Scale Inductively-Powered Light-Directivity-Enhanced Highly-Linear Bidirectional Optogenetic Neuro-Stimulator”, IEEE Custom Integrated Circuits Conference (CICC), Boston, MA, March 2020. 

Here is the abstract:

A mm-scale self-contained bidirectional optogenetic stimulator is presented. A novel LED driving circuit is employed allowing for fully-linear control of optical stimulation with the smallest reported 200mV headroom, significantly boosting the electrical-to-optical energy-conversion efficiency. The energy efficiency is further improved (30.46x) by custom-designed light-directivity-enhancing printed ulenses. In addition to the two stimulation channels, the SoC integrates two recording channels and is powered through an on-chip coil. Electrical, optical, and in-vitro measurement results are reported.

Four papers from ICSL members (graduate and undergraduate students) have been accepted for lecture presentation in IEEE ISCAS 2020, Seville, Spain. Congrats everyone!

• T. Yousefi, H. Kassiri, “A 3.12pJC2 Ultra-Low-Power Direct-ADC Multi-Range Temperature Sensor for IoT Nodes”, accepted for lecture presentation, IEEE ISCAS, Seville, Spain, May 2020.
• F. Eshaghi, E. Najafi Aghdam, H. Kassiri, “A Multi-Feature Nonlinear-SVM Seizure Detection Algorithm with Patient-Specific Channel Selection and Feature Customization”, accepted for lecture presentation, IEEE ISCAS, Seville, Spain, May 2020.
• A. Dabbaghian, H. Kassiri, “An 8-Channel 0.45mm2/channel EEG Recording IC with ADC-Free Mixed-Signal In-Channel Motion Artifact Detection and Removal”, accepted for lecture presentation, IEEE ISCAS, Seville, Spain, May 2020.
• R. Karimi, H. Kassiri, “A Multi-Feature Nonlinear-SVM Seizure Detection Algorithm with Patient-Specific Channel Selection and Feature Customization”, accepted for lecture presentation, IEEE ISCAS, Seville, Spain, May 2020

This month, two of our Master’s students, Alireza Dabbaghian and Tayebeh Yousefi successfully defended their Master’s thesis. We are delighted that they have decided to continue their work in ICSL as PhD students.

Thesis Titles:

Alireza: Integrated Circuits and Systems for A Fully-Flexible Wireless Ambulatory EEG Monitoring and Diagnostics Headband

Tayebeh: Fully-Implantable Self-Contained Dual-Channel Electrical Recording and Directivity-Enhanced Optical Stimulation System on A Chip

Congratulations Alireza and Tayebeh.

ICSL’s undergraduate member, M. Reza Karimi, won the first place award for the best presentation in the Lassonde’s undergraduate research conference. More info here: http://www.lassondeundergraduateresearch.com/2019-summer-research-at-lassonde/

His research was on the design of “a patient-specific AI-based seizure detection algorithms”

Update (January 2020): Reza’s work was accepted as a conference paper in IEEE ISCAS 2020 that will be presented in May 2020 in Seville, Spain:

R. Karimi, H. Kassiri, “A Multi-Feature Nonlinear-SVM Seizure Detection Algorithm with Patient-Specific Channel Selection and Feature Customization”, accepted for lecture presentation, IEEE ISCAS, Seville, Spain, May 2020.

Congrats Reza!
