Abstract: This paper presents a compact and energy efficient noise-shaping successive-approximation-register (NS-SAR) analog-to-digital converter (ADC) based on the error-feedback (EF) structure. Different from most prior works adopting the cascaded integrator feed-forward (CIFF) structure, the proposed architecture… read more here.
