Metastablility in SAR ADCs

Abstract

The fundamental limitation of Nyquist analog-to-digital converter (ADC) architectures toward high speed is metastability. It refers to the inability of a latched comparator to produce a valid decision in a certain available time. This issue is usually severe in high-speed successive approximation register (SAR) ADCs due to their serial conversion scheme… (More)
