Current-Sensing Techniques Video

Abstract - Current-sensing is an essential part of a wide range of applications from hand-held products to the electro-mobility drivetrains. The state of charge in a battery and the control of an electromotor or a power converter have speci?c demands for dynamic-range, precision, speed, isolation, size, and cost. This tutorial provides an overview of the principles of operation and readout techniques for the two current-sensing approaches: Contacted (shunt-based) and contactless (Hall, ?uxgate, transformer, AMR/GMR based).
Biography - Mahdi Kashmiri received his B.Sc. from Tehran University and his M.Sc. and Ph.D. in Microelectronics from Delft University of Technology, Delft, The Netherlands. From 2010 to 2016 he was with Texas Instruments Inc. in Delft and Santa Clara locations, where he worked on precision products including AFEs for low-power ECG, shunt-based current and voltage monitor, contactless current sensor based on integrated Fluxgate and automotive and industrial ultrasound. Since 2016 he has been with the Mixed-signal ASICs group of Robert Bosch Research and Technology Center in Sunnyvale, CA, where he works on ASICs for automotive Lidar. He received the ESSCIRC 2009 Young Scientist Award and is an ISSCC member of the Analog technical program committee.
