Pixel circuit design of CMOS image sensor
- 物理技术－会议论文 
A new pixel circuit that converts the analog light intensity into a digital code was presented in this paper. It consists of four components: a photo-transducer. a preamplifier, a sample&hold (S&H) circuit and a one-bit A/D converter. Each circuit of the components was designed with specific parameters. After simulating the whole pixel circuit with a standard CMOS, this pixel circuit is found to have advantages of low distortion low power consumption and output digital signal.
