description Digital-to-analog converter (DAC) circuits employing resistor rotator circuits configured to be included in analog-to-digital converter (ADC) circuits are disclosed. In one aspect, a DAC circuit includes multiple DAC stages, each of which may be configured to generate one or more DAC analog signals corresponding to selected resistances within the DAC stage. Each DAC stage is configured to receive a corresponding top and bottom voltage. Each DAC stage is configured to generate a number of DAC analog signals based on the corresponding top voltage and the corresponding bottom voltage, as well as on the selected resistance of the DAC stage. Each DAC stage includes an adjusting circuit comprising a resistance configured to adjust a resistance of the corresponding DAC stage such that a parallel combination of the resistance of the adjusting circuit and a resistance of a next DAC stage is maintained at an ideal resistance level.
