Modern data converters generally operate on ±5V (dual supply), +5V or +3V (single supply). In fact, the number of +3V devices is rapidly increasing because of many new markets such as digital cameras, camcorders, and cellular telephones. This trend has created a number of design and applications problems which were much less important in earlier ……
