A 0.6-V 2-2 cascaded audio delta-sigma ADC is described. It uses a resistor-based sampling technique which achieves high linearity and low-voltage operation without subjecting the devices to large… (More)
A 2-2 MASH ADC consumes 1mW from a 0.6V supply. It utilizes a local feedback loop for large input range, and switched-RC integrators to achieve high linearity without clock boosting or bootstrapping.… (More)
Low-voltage, low-power and medium-accuracy analog-to-digital converters (ADCs) are essential components in portable devices. Low-voltage operation of these ADCs poses three major challenges. First,… (More)
