본 논문에서는 CMOS 이미지 센서(CIS)에 사용되는 열 병렬 아날로그-디지털 변환기(ADC)의 아키텍처와 토폴로지를 검토하고 성능 지수(FoM) 기반 열 병렬 ADC를 사용하는 CIS의 성능에 대해 다음과 같은 사항을 고려하여 논의합니다. 낮은/중간 및 높은 픽셀 속도 영역에서 다르게 동작하는 노이즈 모델. 다양한 성능 요소를 고려한 다양한 FoM이 정의됩니다. 정의된 FoM은 4가지 유형으로 분류되는 열-병렬 ADC를 사용하여 보고된 CIS의 조사 데이터에 적용됩니다. 단일 기울기, SAR, 순환 및 델타 시그마 ADC. (잡음)으로 정의되는 FoM2낮은/중간 및 높은 픽셀 속도 영역에 대해 별도로 (전력)/(픽셀 속도)는 모든 픽셀 속도에서 CIS 성능의 최전선을 잘 설명합니다. (잡음)으로 정의된 FoM 사용2(전력)/(장내 동적 범위)(픽셀 속도), 확장된 동적 범위 CIS에 대해 최근 보고된 기술의 효율성이 명확해졌습니다.

Abstract: This paper reviews architectures and topologies for column-parallel analog-to-digital converters (ADCs) used for CMOS image sensors (CISs) and discusses the performance of CISs using column-parallel ADCs based on figures-of-merit (FoM) with considering noise models which behave differently at low/middle and high pixel-rate regions. Various FoM considering different performance factors are defined. The defined FoM are applied to surveyed data on reported CISs using column-parallel ADCs which are categorized into 4 types; single slope, SAR, cyclic and delta-sigma ADCs. The FoM defined by (noise)2(power)/(pixel-rate) separately for low/middle and high pixel-rate regions well explains the frontline of the CIS' performance in all the pixel rates. Using the FoM defined by (noise)2(power)/(intrascene dynamic range)(pixel-rate), the effectiveness of recently-reported techniques for extended-dynamic-range CISs is clarified.
