Speaker

Dr. Minchul Lee (Samsung Electronics), Dr. Long Yan (Samsung Electronics)

Place

Wooribyul Seminar Room (B/D E3-2 , #2201 )

Overview:

Seminar 1 – In order to apply gas sensor to IoT and mobile equipment, there is movement to reduce the size and power consumption of gas sensor (e-nose). In the future, studies are being conducted to produce ICs that can be used for healthcare and diagnosis through ppb level resolution. This seminar introduces E-nose trend, application field, gas sensor technology and LSI E-nose technology.

Seminar 2 – Smart healthcare is shifting the paradigm from traditional diagnostics and therapy to disease prevention and disease interception. Use of wearable device such as health patch tracking health parameters and behavior over extended period of time may turn to this into reality. This drives low-power and low-noise analog IC design for bio-signal measurement. This talk focuses on the instrumentation amplifiers and readout circuits for measuring bio-potential signals. Fundamentals of electrode-tissue interface and signal integrity problems are discussed first. A large part of this talk is on the design of sensor interface circuits with different topology.   

 

Profile:

Minchul Lee received the M.S. and Ph.D. degrees, both in electrical engineering from Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea, in 2001 and 2008 respectively. Since December 2008, he joined System LSI of Samsung Electronics, Hwaseong, South Korea.

Long Yan received the M.S. and Ph.D. degrees, both in electrical engineering from Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea, in 2009 and 2011 respectively. In 2010, he was with Microsystems Technology Laboratories in Massachusetts Institute of Technology (MIT), Cambridge, MA, USA, as a visiting student, where he developed a multi-channel, low-power EEG readout front-end for patient-specific seizure classification. From 2011 to 2014, he has been with IMEC, Leuven, Belgium, as a Senior Scientist. In IMEC, he led to develop multiple low-power mixed-mode circuits for pacemakers, smart watches, and health patches. Since December 2014, he joined System LSI of Samsung Electronics, Hwaseong, South Korea. From 2015, Dr. Yan serves on the technical program committee of IEEE International Solid State Circuit Conference (ISSCC). He is IEEE senior member and he serves as secretary of ISSCC Far East regional committee and Liaisons of ISSCC industry committee.
