Kenneth Carless Smith (May 8, 1932 – October 29, 2023) was a Canadian electrical engineer and academic. He was a Professor Emeritus, University of Toronto, cross-appointed to the departments of electrical and computer engineering, mechanical and industrial engineering, computer
science, and the faculty of information science. Smith died on October 29, 2023, at the age of 91.
On 14 May 2024 an event in memory of Prof. Smith was held in Toronto called "The Joy of Circuit Design: Honouring the Life and Memory of K.C. Smith". It included presentations by a variety of people related to Prof. Smith and featured his former graduate students: Prof. Adel Sedra and Bill Buxton.
Prof. Smith was affectionately called K.C. by his younger colleagues and also known as the "Pink Professor" for his penchant for wearing a pink hat, pink shirt, and pink accessories.




Academic career


Smith received the Bachelor of Applied Science degree
from the Division of Engineering Physics (now Division of Engineering Science)
in 1954, the M.A.Sc in electrical engineering in 1956, and the Ph.D. in Physics
in 1960, all from the University of Toronto.
From 1954 to 1955 he served with Canadian National Telegraphs as a Transmission
Engineer. In 1956, Smith joined the Computation Centre, University of Toronto,
as Research Engineer assigned to assist in the development of high-speed
computers at the Digital Computer Laboratory, University of Illinois, Urbana. In
1960, he joined the faculty at the Department of Electrical Engineering at the
University of Toronto as an Assistant Professor. In 1961 he returned the
University of Illinois as an Assistant Professor of Electrical Engineering
where he became Chief Engineer of Illiac II, and of the Illiac III, and
attained the rank of Associate Professor of Computer Science. In 1965 he
returned to the University of Toronto where he attained the rank of full
Professor. He served as Chair of the Department of Electrical Engineering at
the University of Toronto from 1976 to 1981.
Smith's publications are in the areas of electronic circuits, computer architecture,
multiple-valued logic, instrumentation, sensors, machine vision, neural
networks, computer music, human factors and human-computer interfaces,
and databases.
Smith published over 150 scholarly papers.
Smith is the co-author of Microelectronic Circuits (with A.S. Sedra).
Two of his former graduate students are Adel S. Sedra and Bill Buxton.
Smith and Sedra notably invented the current conveyor, a general circuit component similar to an operational amplifier. They also co-wrote
the undergraduate microelectronics textbook Microelectronic Circuits, originally published in 1982 and now in its eighth edition (2020). The textbook has over one million copies in print as of June 1988.
Smith was appointed an advisory professor in communications at Shanghai Tiedao University, Shanghai,
China in 1989. From 1993 to 1998, Smith was a visiting professor of electrical and electronic engineering at the Hong Kong University of Science and Technology, where he was founding director of its computer engineering department.

Service


Smith was the general Chairman of the 1973 IEEE International Symposium for Circuits and Systems. He has
also contributed to the IEEE International Solid-State Circuits Conference as member of the Program Committee and member of the Executive Committee and Awards Chairman. He was also the Chairman of the Publications Council of the Canadian Society of Electrical Engineering
(CSEE), and a Director of the Canadian Society for Professional Engineers (CSPE).




Industry


Smith co-founded and was principal scientist at Z-Tech, a medical-instrumentation company that
developed bio-impedance measurement devices for the detection of breast cancer.




Awards and honors


Smith was elected fellow of the Institute of Electrical and Electronics
Engineers (1978) "for contributions to digital circuit design" and became a Life Fellow in 1996.
In 1984, he received the IEEE Computer Society Certificate of Appreciation "for contributions to multiple-valued circuit and device technology".
In 2009, he received the IEEE Canada Computer Medal "for lasting technical and educational contributions to electronics for computing".
An anonymous former student donated $75,000 to establish the
Kenneth Carless Smith Engineering Science Research Fellowship, which is awarded
yearly to a student or students in the Engineering Science program at the University of
Toronto.
In 2011, he received the Lifetime Achievement Award from Information Technology Association of Canada (ITAC). He also received University of Toronto Faculty of Applied Science and Engineering Alumni Medal in 2011.
In 2012, the "Kenneth C. Smith Early Career Award for Microelectronics
Research" was created by the International Symposium on Multiple-Valued Logic
to honor Smith for his contribution to the field of multiple-valued logic.
In 2014, Kenneth C. Smith and Laura Fujino were presented with the Annual Creativity in Electronics (ACE) Award, selected by a panel of EDN and EE Times editors.
Other awards include:

IEEE International Solid-State Circuits Service Award, 2000
