An Incremental Noise-Shaping Pipeline ADC With Single-Amplification-Based kT/C Noise Cancellation Technique 150 150
Author(s): Zongnan Wang, Bingrui Li, Jiajun Tang, Zhongyi Wu, Haoyang Luo, Yuan Wang, Xiyuan Tang

Abstract:

This article presents an incremental noise-shaping (NS) pipeline analog-to-digital converter (ADC) featuring a single-amplification-based kT/C noise cancellation technique. By pre-amplifying the frontend sampling kT/C noise onto the capacitive digital-to-analog converter (CDAC) of the backend NS successive approximation register (SAR) quantizer, the proposed architecture eliminates the repeated amplifications typically …

Abstract:

This article presents a two-step incremental analog-to-digital converter (ADC) that achieves high resolution and energy efficiency while substantially easing the input driving constraints and interstage gain variation. By employing a level-shifted sub-ranging architecture with an input-tracking (IT) feature, the design obviates direct input sampling, thereby significantly relaxing the demands on …
