DOI: 10.1109/tcsii.2023.3296453
Abstract: This brief presents a 70.6-dB SNDR pipeline-successive approximation register (SAR) analog-to-digital converter (ADC) that utilizes an Adaptive-Region-Selection (ARS) technique to linearize the residue amplification. The proposed technique avoids the complex high-order nonlinearity detection and correction… read more here.
