Beschreibung
This book provides readers with a single-source reference to current sensing integrated circuit design. It is written in handbook style, including systematic guidelines and implementation examples. The authors focus on the implementation of wide-bandwidth current sensing on a single microchip, toward usage in applications such as sensing, control and optimization of the energy flow in growth areas like industrial electronics, renewable energies, smart grids, electromobility and the Internet of Things.
Provides readers with a comprehensive, all-in-one source for current sensing integrated circuit design, including implementation examples;Discusses modeling and optimization of on-chip Rogowski coil and Hall sensor in both lateral and vertical orientation;Includes noise reduction techniques, such as auto-zeroing and chopping;Covers open-loop and closed-loop sensor front-end design;Presents the first on-chip current sensorwith a planar coil placed besides a power line to measure internal signal currents and the first off-chip current sensor with a helix-shaped coil for external signal currents in the multi-MHz region.
Autorenportrait
Tobias Funk received his B.Eng. degree from the University of Applied Science Esslingen, Germany, in 2011, the M.Sc. degree from Reutlingen University, Germany, in 2013 and the Ph.D. degree (Summa Cum Laude) from Leibniz University Hannover, Germany, in 2019. Since April 2019, he is with the research and development department at ARBURG GmbH + Co KG. His current research interests include integrated power management, fully integrated wide-bandwidth current sensing and discrete high-voltage driving circuits. He invented three patents.
Bernhard Wicht has 20+ years of experience in analog and power management IC design. He received the Dipl.-Ing. degree in electrical engineering from TU Dresden, Germany, in 1996 and the Ph.D. degree (Summa Cum Laude) from TU Munich, Germany, in 2002. Between 2003 and 2010, he was with Texas Instruments, Germany, responsible for the design of automotive power management ICs. He was a professor at Reutlingen University and he is currently heading the Chair for Mixed-Signal IC Design at Leibniz University Hannover, Germany. Dr. Wicht was co-recipient of the 2015 ESSCIRC Best Paper Award and of the 2019 First Prize Paper Award of the IEEE Journal of Emerging and Selected Topics in Power Electronics. In 2018, he received the faculty award for excellent teaching at his university. He invented seventeen patents with several more pending. He is currently a SSCS Distinguished Lecturer and a member of the ISSCC Technical Program Committee.

Informationen zu E-Books
„E-Book“ steht für digitales Buch. Um diese Art von Büchern lesen zu können wird entweder eine spezielle Software für Computer, Tablets und Smartphones oder ein E-Book Reader benötigt. Da viele verschiedene Formate (Dateien) für E-Books existieren, gilt es dabei, einiges zu beachten.
Von uns werden digitale Bücher in drei Formaten ausgeliefert. Die Formate sind EPUB mit DRM (Digital Rights Management), EPUB ohne DRM und PDF. Bei den Formaten PDF und EPUB ohne DRM müssen Sie lediglich prüfen, ob Ihr E-Book Reader kompatibel ist. Wenn ein Format mit DRM genutzt wird, besteht zusätzlich die Notwendigkeit, dass Sie einen kostenlosen Adobe® Digital Editions Account besitzen. Wenn Sie ein E-Book, das Adobe® Digital Editions benötigt herunterladen, erhalten Sie eine ASCM-Datei, die zu Digital Editions hinzugefügt und mit Ihrem Account verknüpft werden muss. Einige E-Book Reader (zum Beispiel PocketBook Touch) unterstützen auch das direkte Eingeben der Login-Daten des Adobe Accounts – somit können diese ASCM-Dateien direkt auf das betreffende Gerät kopiert werden.
Da E-Books nur für eine begrenzte Zeit – in der Regel 6 Monate – herunterladbar sind, sollten Sie stets eine Sicherheitskopie auf einem Dauerspeicher (Festplatte, USB-Stick oder CD) vorsehen. Auch ist die Menge der Downloads auf maximal 5 begrenzt.
