Thermal and Reference Noise Analysis of Time-Interleaving SAR and Partial-Interleaving Pipelined-SAR ADCs

This paper analyzes the thermal and reference noises of two types of successive-approximation-register (SAR) analog-to-digital converters (ADCs): the time-interleaving (TI) and the partial-interleaving (PI) Pipelined. The thermal noise is investigated with accurate estimation by deriving closed-form expressions according to the noise equivalent models on different phases. Additionally, the design ...
