Hybrid-Design of Analog-to-Digital Converters Slides and Transcript

Abstract - Traditionally, ADC architectures have been sorted into distinct categories such as FLASH, SAR, pipeline, and delta-sigma. Recently, improvements in ADC power, speed, and resolution have been enabled by hybrid approaches that combine techniques from many ADC architectures. Further, this trend of hybrid design is extended beyond the choice of quantizer to include a mix of circuit topologies in key ADC building blocks. The resulting degrees of freedom allow designers to fully optimize their converters, leading to performance levels beyond what can be achieved with conventional architectures. This tutorial will start with a general overview of key ADC architectures (e.g. Flash, SAR, pipeline and delta-sigma), highlighting basic operation and design trade-offs. Second, the architectural hybrid designs in consideration of various quantizer options will be discussed. Last, illustrative examples of hybrid circuit topologies and techniques will be discussed, with emphasis on design choices that enabled performance benefits for the specific application of interest.
