Abstract
Embodiments of an analog-to-digital converter (ADC), resistive digital-to-analog converter (DAC) circuits, and methods of operating an ADC are disclosed. In an embodiment, an analog-to-digital converter includes a DAC unit configured to convert a digital code to a first voltage in response to an input voltage of the ADC, a comparator configured to compare the first voltage with a second voltage to generate a comparison output, and a logic circuit configured to generate the digital code, to control the DAC unit based on the comparison output, and to output the digital code as a digital output of the ADC. The DAC unit includes a capacitive DAC and multiple resistive DACs. Each of the resistive DACs is connected to the first voltage through a respective capacitor.
