DR. KARABI BISWAS
Associate Professor, Electrical Engineering Department, IIT Kharagpur
Dr. Karabi Biswas completed her undergraduate studies in Instrumentation Engineering from IIT Kharagpur, Kharagpur in 1992. She did her M. Tech from Jadavpur University in 2000 and PhD in the area of Sensor Development at Indian Institute of Technology (IIT) Kharagpur. As a member of Sensors Development research group, currently, she is in the faculty of Electrical Engineering Department, Indian Institute of Technology, Kharagpur.
Dr. Karabi Biswas is an Associate Editor of "International Journal of Circuit Theory and Applications".
Dr. Karabi Biswas is a Review Editor of "Frontiers in Electronics".
Dr. Karabi Biswas is a member of IEEE, USA, System Society of India and Indian Dairy Association.
Research Interest: Dr. Karabi Biswas’s research interests are “Sensor development”, “Instrument system design” and “Study of fractional order systems”.
She is one of the earliest scientists who could realize a fractional order element with tunable parameters. The device is a low cost one and can be easily manufactured which makes it a potential candidate to become the fourth element in electrical circuits apart from the existing resistor, capacitor and inductor. The other notable feature of the device is that it can be used as a sensor to sense the ionic property of liquid medium. She has successfully used in-house developed fractional order element to develop fractional order differentiator, integrator, filters which contributes to the development of a parallel branch in mathematics and engineering comprising of fractional order differential equations.
She is instrumental in developing multidisciplinary research in electrical engineering.
Her research on fractional order element now extends to the analysis of origination of its fractional order behavior, its customization and its packaging which require in-depth knowledge in physics, chemistry, material science and engineering. The main vision of the research is to develop a commercially viable element which will be considered as the fourth element in electrical engineering apart from the existing resistor, capacitor and inductor.
She also plans to develop low cost instrumentation system using the device as a sensor for health care and environmental monitoring. In the process she is connecting with various stakeholders like industry, other (national/international) universities, funding agencies; graduate students to develop a new area in science and engineering comprising fractional order system.
DR. PRADIP MANDAL
Professor, Electronics & Electrical Communication Engineering Department, IIT Kharagpur
Dr. Pradip Mandal received the B.E. degree in Electronics and Telecommunication Engineering from the Bengal Engineering College, Shibpur, India, in 1989, and the M.E. and Ph.D. degrees in Electrical Communication Engineering from the Indian Institute of Science, Bangalore, India, in 1991 and 1999, respectively. In 1997, he was with Motorola India Electronics. From 1998 to 2002, he was with Philips Semiconductors. In 2002, he was with the Alliance Semiconductor, where he was involved in dc–dc converters and power supervisory circuits. Since 2004, he has been with the Department of Electronics and Electrical Communication Engineering, Indian Institute of Technology Kharagpur, Kharagpur, India, where he is currently a Professor. His current research interests include the design of interface circuits for high-speed data link, design of integrated dc–dc converters, design of analog front-end, and design automation for analog integrated circuits.
Research Interest:
The area of research work is Analog CMOS VLSI Circuit/System Design. Activities in research team can be broadly classified in to two categories. The first one involves architecture development and prototype design of analog circuits/systems in three specific topics namely, Interface unit for high speed data link, On-chip DC-DC converter and Signal acquisition front-end. The second category of work is about developing and prototyping automatable design methodologies for frequently used analog circuits/systems.
For high speed data link that have been proposed a number of power efficient high speed data receivers and transmitters with active terminator. Some of his design also enables simultaneous two-way data transmission over a common link.
Dr. Mandal and his team have proposed a switching scheme for switched-capacitor based DC-DC converter which improves the power efficiency by 5-10%. They have proposed a scheme of dynamically adjusting switching frequency of switched-capacitor based DC-DC converter which helps to maintain high power efficiency across wide range of load current. Both, the switching scheme and switching frequency adjustment are generic enough to be applied for buck and boost converters.
They have proposed a Geometric Programming (GP) based circuit sizing method for optimum design. The sizing method is very fast and robust. The GP based optimization method has been upgraded to address practical design considerations and issues in sub-micron technologies. Prototype codes have been implemented to design a number of practical circuit meeting competitive specifications. They also have proposed a design methodology for analog system utilizing the GP-based circuit sizing method. A prototype code has been implemented to design Analog-to-Digital Converter (ADC). To design an ADC, normally, an experienced designer takes more than 3 months, which is performed by the prototype code in 6 hours.
