SINGLE-SUPPLY AMPLIFIERS
Adolfo Garcia

Over the last several years, single-supply operation has become an increasingly
important requirement as systems get smaller, cheaper, and more portable.
Portable systems rely on batteries, and total circuit power consumption is an
important and often dominant design issue, and in some instances, more important
than cost. This makes low-voltage/low supply current operation critical; at the same
time, however, accuracy and precision requirements have forced IC manufacturers
to meet the challenge of “doing more with less” in their amplifier designs.
