Cmos Voltage References - An Analytical and Practical Perspective

Informationen zum Autor Chi-Wah Kok, Canaan Microelectronics Corporation Limited, China Chi-Wah Kok obtained his degree from the University of Wisconsin Madison. Since 1992, he has been working with various semi-conductor companies, research institutions and universities, which include AT&T Labs Research, Holmdel, SONY U.S. Research Labs, Stanford University, Hong Kong University of Science and Technology, Hong Kong Polytechnic University, City University of Hong Kong, and Lattice Semiconductor. In 2006, he founded Canaan Microelectronics Corp Ltd., a fabless IC company with products in mixed signal IC for consumer electronics. He has extensively applied signal processing techniques to improve the circuit topologies, designs, and fabrication technologies within Canaan. This includes the application of semidefinite programming to circuit design optimization, abstract algebra in switched capacitor circuit topologies improvement, and nonlinear optimization methods to optimize high voltage MOSFET layout and fabrication. Wing-Shan Tam, Canaan Microelectronics Corp Limited, China Wing-Shan Tam received her BEng degree in electronic engineering from The Chinese University of Hong Kong, and MSc degree in electronic and information engineering from The Hong Kong Polytechnic University, and PhD degree in electronic engineering from the City University of Hong Kong in 2004, 2007, and 2010, respectively. Currently, she is the Engineering Manager of Canaan Microelectronics Corp Ltd., and she has been working with CMOS circuit design since 2004. Her research interests include mixed-signal integrated circuit design for data conversion and power-management. Klappentext A practical overview of CMOS circuit design, this book covers the technology, analysis, and design techniques of voltage reference circuits. The design requirements covered follow modern CMOS processes, with an emphasis on low power, low voltage, and low temperature coefficient voltage reference design. Dedicating a chapter to each stage of the design process, the authors have organized the content to give readers the tools they need to implement the technologies themselves. Readers will gain an understanding of device characteristics, the practical considerations behind circuit topology, and potential problems with each type of circuit.Many design examples are used throughout, most of which have been tested with silicon implementation or employed in real-world products. This ensures that the material presented relevant to both students studying the topic as well as readers requiring a practical viewpoint.* Covers CMOS voltage reference circuit design, from the basics through to advanced topics* Provides an overview of basic device physics and different building blocks of voltage reference designs* Features real-world examples based on actual silicon implementation* Includes analytical exercises, simulation exercises, and silicon layout exercises, giving readers guidance and design layout experience for voltage reference circuits* Solution manual available to instructors from the book's companion websiteThis book is highly useful for graduate students in VLSI design, as well as practicing analog engineers and IC design professionals. Advanced undergraduates preparing for further study in VLSI will also find this book a helpful companion text.
