A digital‐domain dual‐calibration for single‐ended successive approximation register analogue‐to‐digital converters (SAR ADCs) is presented. The dual‐calibration combines digital error correction with capacitor mismatch calibration to compensate the decision errors and improve capacitor matching. Simulation results show that the proposed digital‐domain dual‐calibration technique can significantly improve signal‐to‐noise‐and‐distortion and spurious‐free dynamic range for the single‐ended SAR ADC.
