Project description
 Technology scaling has made designing traditional ADCs increasingly challenging. VCO-based ADCs have emerged as a promising alternative, allowing ADC performance to scale with technology thanks to their near-digital nature. However, existing high-bandwidth VCO-based ADCs have only demonstrated first-order noise shaping, limiting their performance. This project aims to develop ADCs achieving higher-order noise shaping at bandwidths exceeding
