Current sources and voltage references provide fixed, well-regulated levels of current or voltage within a circuit. These are two of the most important building blocks of analog circuits, and are typically used in creating most analog IC designs.
Part 1 shows the reader how current sources are created, how they can be optimized, and how they can be utilized by the OEM circuit designer. The book serves as a must-have reference for the successful development of precision circuit applications. It shows practical examples using either BJTs, FETs, precision op amps, or even matched CMOS arrays being used to create highly accurate current source designs, ranging from nanoAmps to Amps. In each chapter the most important characteristics of the particular semiconductor type being studied are carefully reviewed. This not only serves as a helpful refresher for experienced engineers, but also as a good foundation for all EE student coursework, and includes device models and relevant equations.
Part 2 focuses on semiconductor voltage references, from their design to their various practical enhancements. It ranges from the simple Zener diode to today’s most advanced topologies, including Analog Devices’ XFET and Intersil’s FGATM (invented while this book was being written). Over 300 applications and circuit diagrams are shown throughout this easy-to-read, practical reference book.
* The ONLY book available specifically on Current Sources, and the most up-to-date book anywhere on all of today’s Voltage Reference topologies
* A complete guide to an often overlooked but vital aspect of analog circuit design – now of increasing importance in any high resolution A/D and D/A applications, including communications technologies
