본 논문에서는 동영상의 특징을 이용한 저전력 비디오 A/D 변환 기법을 제시한다. 일반적인 비디오 시퀀스의 인접 프레임과 각 비디오 프레임의 인접 픽셀은 높은 상관 관계를 갖습니다. 이 속성은 비디오 A/D 변환에 효과적으로 사용되어 비교기 수와 그에 따른 전력 소비를 줄입니다. 반복적인 A/D 변환이 예측 오차의 로그 순서로 수렴되도록 기준 전압 세트가 비교기 어레이에 제공됩니다. 표준 동영상을 사용한 시뮬레이션 결과, 테스트한 모든 동영상에 대해 A/D 변환의 평균 반복 횟수가 3회 미만인 것으로 나타났습니다. 제안된 12b A/D 변환기에서는 일반적으로 비디오 응용 분야에 사용되는 1단계 플래시 A/D 변환기에 비해 비교기 수를 약 5/XNUMX로 줄일 수 있다. A/D 변환기는 특히 CMOS 이미지 센서에 통합하는 데 유용합니다.

vol. E82-C, no. 9, pp. 1764-1771, September 1999, doi: .
Abstract: This paper presents a low-power video A/D conversion technique using features of moving pictures. Neighboring frames in typical video sequences and neighboring pixels in each video frame are highly correlated. This property is effectively used for the video A/D conversion to reduce the number of comparators and the resulting power consumption. A set of reference voltages is given to a comparator array so that the iterative A/D conversion converges in the logarithmic order of the prediction error. Simulation results using standard moving pictures showed that the average number of iterations for the A/D conversion is less than 3 for all the moving pictures tested. In the proposed 12 b A/D converter, the number of comparators can be reduced to about 1/5 compared with that of the two-step flash A/D converters, which are commonly used for video applications. The A/D converter is particularly useful for the integration to CMOS image sensors.
