DR Loss-Free Dithering-Based Digital Background Linearity Calibration for SAR-Assisted Multi-Stage ADCs With Digital Input-Interference Cancellation

DR Loss-Free Dithering-Based Digital Background Linearity Calibration for SAR-Assisted Multi-Stage ADCs With Digital Input-Interference Cancellation

In this paper, we propose a correlation-based background linearity calibration technique to digitally correct the bit weights in successive approximation register (SAR)-assisted analog-to-digital converters (ADCs). Unlike typical dithering-based calibration techniques in which signal dynamic range (...
