“…Hybrid third-order implementations combining EF and CIFF have also been reported [32,33], where both feedback and feed-forward addition are included. Because of the flexibility in the implementation of the IIR filter, recent resonators, CRFF (Cascade Resonator Feed-Forward), have been proposed [34], but also one that includes the resonator in a hybrid architecture (active-passive), achieving an improvement in BW [35]. A comparison of the cascaded implementations can be seen in Table 2.…”

A general overview of Noise-Shaping Successive Approximation Register (SAR) analog-to-digital converters is provided, encompassing the fundamentals, operational principles, and key architectures of Noise-Shaping SAR (NS SAR). Key challenges, including inherent errors in processing circuits, are examined, along with current advancements in architecture design. Various issues, such as loop filter optimization, implementation methods, and DAC network element mismatches, are explored, along with considerations for voltage converter performance. The design of dynamic comparators is examined, highlighting their critical role in the SAR ADC architecture. Various architectures of dynamic comparators are extensively explored, including optimization techniques, performance considerations, and emerging trends. Finally, emerging trends and future challenges in the field are discussed.

“…Y porque existe Alim. flexibilidad en la implementación del filtro IIR, también se ha apostado por propuestas que incluyan resonadores, CRFF (Cascade Resonator Feed-forward), como el desarrollo que implementó la conexión en cascada EF [37], pero también la que incluye el resonador en una arquitectura híbrida (activapasiva), alcanzando una mejora en BW [38]. Una comparativa de las implementaciones puede apreciarse en la Tabla III.…”
