用于CMOS图像传感器的12位低功耗单斜坡模数转换器设计
12Bit Low Power Single Slope ADC Design for CMOS Image Sensor
摘要
Abstract
A high quantization resolution and low power consumption single slope ADC scheme, for CMOS image sensor applications is proposed. The proposed scheme is composed of the variable gain amplifier,preamplifier and the dynamic latch comparator. Compared to the prior art structure, the proposed circuit can achieve a reasonable noise performance, consume less power and occupy smaller chip area. This proposed ADC is implemented as a column-parallel ADC array inside a fabricated CMOS image sensor chip.The experimental results verify the conception proposed in this paper.关键词
