Abstract

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 and hold 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.
