Inhalt:
Current Sources and Voltage References provides 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 mat
