Self-Dithering Technique for High-Resolution SAR ADC Design

Lin He, Lele Jin, Jiaqi Yang, Fujiang Lin et autres

In this brief, a high-resolution successive-approximation-register analog-to-digital-conversion architecture for biomedical data acquisition is proposed. A filtered least-significant-bit segment is employed as a dither to improve the resolution. Theoretical analysis and behavioral simulations show that the error of a most-significant-bit segment can be …
