Power-Saving A/D Conversion for High-Accuracy Measurements (Download)
A typical application in electrical engineering is the recording of physical quantities by sensors and forwarding these quantities to a microcontroller for further processing. Analog-to-digital converters (ADCs) are needed to convert the analog sensor output signals into digital signals. In high-precision applications, either successive-approximation-register (SAR) ADCs or sigma-delta ADCs are used. With low-power applications, every milliwatt that can be saved counts.
