Current-Mode Circuit Design: Recent Advances And Expected Directions
Abstract:
Current-mode circuits attracted considerable attention in the past. In this talk a short history of current-mode circuits is presented with recent advances in the last two decades. Growing publications in this area of electronic circuits are discussed using classifications and comparisons with the classical opamp based realizations. Then a sub-class of externally linear internally non-linear circuits is revisited. A brief history log-domain filters, starting from Adams 1979 discovery will be given. Potential advantages of these circuits also working in current-mode are discussed. Freys contributions for a systematic design procedure in 1993 and 1996 are included in the talk. In light of historical developments and considering current trends in low-voltage, low-power design with higher frequency of operation requirements, some near future expectations in this area are mentioned. Moreover taking todays technological constraints in integrated circuit technology, some possible solutions with parasitic elements used as an advantage are suggested.
Oguzhan CICEKOGLU received the B.Sc. and M.Sc. degrees from Bogazici University and the PhD. degree from Istanbul Technical University all in Electrical and Electronics Engineering in 1985, 1988 and 1996 respectively. He served as lecturer at the School of Advanced Vocational Studies Electronics Prog. of Bogazici University where he held various administrative positions between 1993 and 1999. He has also given lectures at the Turkish Air Force Academy. He was with the Biomedical Engineering Institute of the Bogazici University between 1999 and 2001. Then he joined the Electrical and Electronics Engineering Department of the same University where he became a professor. Between 2007 and 2010 he served as the Dean of Engineering at Corlu Engineering Faculty of Namik Kemal University, Turkey.
Oguzhan Cicekoglu served in organizing and technical committees of many national and international conferences. He was the guest co-editor of two previous Special Issues of the Analog Integrated Circuits and Signal Processing Journal. One of the publications he co-authored in IEEE Transactions on Circuits and Sytems II-Analog and Digital Signal Processing is among the top cited papers listed in IEEE Circuits and Systems Society web page. He received the Research Excellence Award of Bogazici University Foundation in 2004. He served as the co-chair of Amplifiers and Comparators track in 50th IEEE Midwest-Newcas Joint Conference which is held in Montreal-Canada as a track chair in the 52th IEEE Midwest Symposium held in Cancun-Mexico. His current research interests include analog circuits, active filters, analog signal processing applications and current-mode circuits. He is the author or co-author of about 150 papers published in scientific journals or conference proceedings and conducts review in numerous journals including Analog Integrated Circuits and Signal Processing, IEEE CAS-I, IEEE CAS-II, International Journal of Electronics, International Journal of Circuit Theory and Applications, IEE Proceedings Pt.G, ETRI Journal and several others.
