Provides automated digital calibration to compensate for capacitor mismatch and linearity errors, improving conversion accuracy while reducing calibration complexity and manual intervention.

SAR-ADC performance may be affected by capacitor mismatch and linearity errors, resulting in inaccurate data conversion and reduced overall measurement and signal-processing performance.

Provides a digital SAR-ADC calibration mechanism that uses comparator-output counting, majority-decision logic, state control and tunable-capacitor adjustment to correct capacitor-related linearity errors and improve data-conversion accuracy.

Introduces a digital calibration mechanism combining comparator-output counting, majority-decision logic, state control and tunable-capacitor adjustment to compensate for capacitor mismatch and improve SAR-ADC linearity.
