SSCS Thailand Chapter Hosts DL Talk on CMOS Image Sensors
and Microelectronics Olympiad Competition

The IEEE Solid-State Circuits Society
(SSCS) Thailand Chapter organized a
seminar, "CMOS Image Sensors," on
26 September 2016 at Chulalongkorn
University. The invited speaker was
SSCS Distinguished Lecturer (DL) Prof.
Makoto Ikeda from the University of
Tokyo, Japan. Prof. Ikeda gave the talk
"Basics of CMOS Image Sensors" and
commented on a student talk "Zero
Bias CMOS Image Sensors." Seminar
attendees consisted of professors
and graduate students who study IC
design and engineers from industry.
The complimentary metal-oxide-
semiconductor (CMOS) image sensor
is now a common device in many
consumer electronic products. Its
structure and circuit design is a good
subject for academic institutions.
Prof. Makoto's lecture covered CMOS
image sensor processes and its noise
characteristics (including thermal
noise, flicker noise, reset noise). He
also covered signal chain from pixel
to column parallel analog-to-digital converters to achieve low-noise
readout as low as 1e-. This lecture
covered some dynamic range extenDigital Object Identifier 10.1109/MSSC.2016.2623062

sion techniques, including multiple
exposure techniques, logarithmic
compression techniques, frequency
conversion techniques, and lowpower techniques. At the end of the
talk, Prof. Ikeda also commented on a
graduate student's presentation on a
low-power CMOS image sensor using
the zero bias technique.
On 19 September, a paper-based
competition was held at Kasetsart University to select a Thailand representative to participate in the 11th Interna-

tional Microelectronics Olympiad 2016
in Armenia. The winner was Pusit Surivavejwongs from Chulalongkorn University. The program was sponsored
by Synopsys and Silicon Craft Technology, a Thai fabless IC design company.
The main Olympiad event was incorporated with IEEE Test Technology Technical Council.

Taipei Chapter Chair Tai-Cheng Lee
said the session attracted many
students as well as analog designers from local integrated circuit
design houses.
