This paper presents a digitally calibrated 12bit 12.5-MS/s successive-approximation-register (SAR) analog-to-digital converter (ADC) intended for low-power wireless communication and medical instrumentation. The performance of the proposed prototype is enhanced by two techniques. A power saving strategy is proposed. Also, several foreground calibration methods for SAR ADCs are proposed to reduce the...
In many applications, such as in battery-operated medical devices or in habitat monitoring sensor networks, special data converters are needed, which can operate on battery or even harvested power. The available power in these devices is very limited, often only a few tens of microwatts. This tutorial discusses some of the design options for such micropower digital-to-analog and analog-to-digital...
