Description
System-on-a-chip (SoC) designs result in a wide range of high-complexity, high-value semiconductor products. As the technology scales towards smaller feature sizes and chips grow larger, a speed limitation arises due to an in creased RC delay associated with interconnection wires. Innovative circuit techniques are required to achieve the speed needed for high-performance signal processing. Current sensing is considered as a promising circuit class since it is inherently faster than conventional voltage sense amplifiers. How ever, especially in SRAM, current sensing has rarely been used so far. Practi cal implementations are challenging because they require sophisticated analog circuit techniques in a digital environment. The objective of this book is to provide a systematic and comprehen sive insight into current sensing techniques. Both theoretical and practical aspects are covered. Design guidelines are derived by systematic analysis of different circuit principles. Innovative concepts like compensation of the bit line multiplexer and auto-power-down will be explained based on theory and experimental results. The material will be interesting for design engineers in industry as well as researchers who want to learn about and apply current sensing techniques. The focus is on embedded SRAM but the material presented can be adapted to single-chip SRAM and to any other current-providing memory type as well. This includes emerging memory technologies like magnetic RAM (MRAM) and Ovonic Unified Memory (OUM). Moreover, it is also applicable to array like structures such as CMOS camera chips and to circuits for signal trans mission along highly capacitive busses.

Person
Maik Kaufmann received the B.Eng. degree in electrical engineering with focus on electronics from the Cooperative State University Baden-Wuerttemberg, Stuttgart, Germany in 2014 and the M.Sc. degree in power and microelectronics from Reutlingen University, Reutlingen, Germany in 2017. He received the Ph.D. degree (Magna Cum Laude) in electrical engineering from Leibniz University Hannover, Germany, in 2021. For his PhD research, he was working on monolithic integration in e-mode GaN technology. After his graduation, he joined the KilbyLabs department of Texas Instruments in Freising in the role of an analog design engineer focusing on circuit design for high-voltage power converters. Dr. Kaufmann co-invented one patent in the area of GaN integration with several more pending.
Bernhard Wicht has 20+ years of experience in analog and power management IC design. He received the Dipl.-Ing. degree from TU Dresden in 1996 and the Ph.D. degree (Summa Cum Laude) from TUMunich in 2002. Between 2003 and 2010, he was with Texas Instruments in Germany, responsible for the design of automotive power management ICs. He was a professor at Reutlingen University and he is currently the head of the Chair for Mixed-Signal IC Design at Leibniz University Hannover, Germany. His research interest includes IC design with focus on power management, gate drivers and high-voltage ICs. 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. Dr. Wicht is a member of the Technical Program Committee of ISSCC, where he is currently the chair of the Power Management subcommittee. He was a Guest Editor of the IEEE Journal of Solid-State Circuits-Special Issue of 2019 ISSCC and a Distinguished Lecturer of the IEEE Solid-State Circuits Society in 2020-2021.
