Analysis of the Effect of Comparator Offset on the ENOB of Charge- Sharing SAR ADCs
No full textThis technical report analyzes the impact of comparator offset on the effective number of bits (ENOB) of charge-sharing SAR ADCs. The authors propose a closed-form expression for the maximum achievable ENOB as a function of the comparator offset voltage, which is verified through behavioral simulations. By modeling the non-linear behavior of the CS ADC due to the comparator offset, the study provides valuable insights into the design guidelines and limitations of this type of ADC, ultimately contributing to the development of more accurate and efficient SAR ADCs for low-power applications
Charge-sharing SAR ADCs for low-voltage low-power applications
No full textThis book introduces readers to the potential of charge-sharing (CS) successive approximation register (SAR) analog-to-digital converters (ADCs), while providing extensive analysis of the factors that limit the performance of the CS topology. The authors present guidelines and useful techniques for mitigating the limitations of the architecture, while focusing on the implementation under restricted power budgets and voltage supplies
