IEEE SSCS Kolkata Chapter Holds Technical Events
During the Fourth Quarter of 2020
T
The IEEE Solid-State Circuits Society
(SSCS) Kolkata Chapter kept active during
the fourth quarter of 2020 with a
variety of events including webinars,
contests for students, and workshops.
Webinar on Bode's Noise Theorem
The webinar " Bode's Noise Theorem and
Its Extension to Periodically Switched
RLC Networks " was presented by Prof.
Shanthi Pavan on 14 August 2020. The
event drew 42 participants.
Abstract
The analog circuit designer is often
faced with the task of evaluating the
total integrated noise in passive RLC networks.
Bode's noise theorem is an efficient
way of performing this evaluation
without running into involved calculations.
Bode's theorem was originally
derived using contour integration.
This talk presents, in a tutorial fashion,
an alternative approach to the Bode
noise theorem and derives an equivalent
result. It turns out that the same result
holds when periodically operated

switches are included in the network,
causing the RLC network to become
periodically time varying. Our
result allows the determination
of total integrated noise
in such networks, traditionally
requiring restrictive
assumptions and intense
algebra, to be obtained
by inspection.
Fourteen papers
were presented
from seven
Student Paper
Contest 2020
A 2020 student paper contest for
undergraduate and postgraduate
students was organized by the SSCS
Kolkata Chapter on 12 September
2020. Fourteen papers were presented
from seven different colleges and
universities around India. The event
was held virtually. The papers were
judged by Prof. C.K. Sarkar, Dr. Kalyan
Koley, and Kamalendu Langal. The
top three papers and best presentation
received awards.
One-Day Workshop: " Circuit
Design Using LTspice "
The SSCS Kolkata Chapter, along with
the MCKV Institute of Engineering
different colleges
and universities
around India. The
event was held
virtually.
(MCKVIE), West Bengal, India, organized
the one-day workshop " Circuit
Design Using LTspice "
on 18 October 2020.
Sagar Mukherjee gave
a talk on present-day
analog circuit design,
and a hands-on s e s -
sion using LTspice was
conducted by Subhasish
Banerjee. The event was
held virtually and attracted
28 participants.
Circuit Design Contest 2020
The SSCS Kolkata Chapter held a circuit
design contest on 7 November
2020. Students were instructed to
present a design document for a
circuit based on a given problem.
Competitors implemented the design
using LTspice, with students
from 10 different colleges and universities
participating in the event
in groups of two. The event was
judged by Richeek Maitra, analog
design engineer, Texas Instruments,
and Banerjee, MCKVIE. The top
two designs were recognized for
their achievement.
