Abstract

This Ph.D. dissertation describes the theory and realization of wide-bandwidth magnetic sensors for current measurements which breach the conventional offset and noise constraints in CMOS processes. These are achieved by several circuit-level and system-level innovations, including the use of three orthogonal ripple reduction loops (RRLs) in spinning-current Hall sensors, a multipath
architecture with double Hall sensors, and a hybrid magnetic sensor system combining Hall sensors and pick-up coils. The prototypes with these techniques have advanced the bandwidth of state-of-the-art CMOS magnetic sensors by more than two orders of magnitude.

Bibliographical note

Junfeng Jiang was born in 1986 in Dalian, China. He received his B.Sc. degree in electrical engineering from Dalian University of Technology, Dalian, China, in 2009, and his M.Sc. degree in microelectronics from Delft University of Technology, Delft, the Netherlands in 2011. He expects to receive his Ph.D. degree from the same university in 2019, for his work on CMOS wide-bandwidth magnetic sensors for contactless current measurements. From 2010 to 2016, he
was a visiting scholar at Texas Instruments (Formerly National Semiconductor Corporation), Delft, where he worked on CMOS wide-bandwidth magnetic sensors. From 2016 to 2017, he was with Texas Instruments Deutschland GmbH, Freising, Germany. Since November 2017, he has been with the sensing group of Texas Instruments, Dallas, USA. His interests include the design of precision analog systems, magnetic sensors and mixed-signal integrated circuits.

Junfeng Jiang received the A-SSCC 2015 Travel Grant, SSCS Predoctoral Achievement Award 2016-2017 and ESSCIRC 2016 Best Paper Award.
