Energy-Efficient Noise-Shaping SAR ADCs for Next-Generation Wireless Communication Systems
The growing demand for high-speed, high-resolution data conversion in next-generation wireless systems calls for Analog-to-Digital Converters (ADCs) that combine low power consumption with enhanced performance. This research focuses on Noise-Shaping SAR ADCs (NS SAR ADCs), which combine the energy efficiency of SAR architectures with resolution comparable to delta-sigma modulators. The work addresses key design challenges in achieving high-resolution, wide-band conversion by developing novel, power-efficient noise-shaping filters and hybrid converter architectures that enhance speed without compromising energy efficiency. By exploring architectural trade-offs and integrating state-of-the-art building blocks into an optimized high-level structure, this research enables a new class of robust, high-performance ADCs tailored for future wireless communication standards.
