Voltage References
Wiley-IEEE Press (Verlag)
978-0-471-14336-9 (ISBN)
Primary topics include:
The complete design of integrated voltage references
Basics of voltage references, from diodes and current mirrors to temperature-dependent current references
Design of zero-order, first-order, second-order, and higher-order reference circuits
State-of-the-art curvature-correction techniques
Practical design issues of integrated references, from error sources and circuit topologies to trimming circuits, package-shift effects, and characterization
Voltage References is an essential book for IC designers, product engineers, test engineers, researchers, and professors, as well as undergraduate and graduate students.
GABRIEL ALFONSO RINCÓN-MORA, PhD, is Adjunct Professor at the Georgia Institute of Technology and a senior designer for Texas Instruments, Inc. He is the author of several journal publications, the inventor of numerous patents, and the designer of many products sold throughout the world.
