Abstract :
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.
