Making Low Power and Low Voltages Work in Analog Design


Abstract: Virtually any digital IC is available in a low-power 3V version today. Analog circuits have traditionally used higher voltage supplies and sometimes dual supplies to achieve higher performance. Generally, it is easier and cheaper to design systems with a single-supply 5V or 3V rail. Lower power operation in low-voltage devices also makes them ideal for battery powered portable instrumentation.
