Abstract
In this paper, the design of a sensor array circuit for edge detection is presented. For this design, a new version of edge detection algorithm is proposed to reduce the complexity of inter-pixel connections and to simplify the circuit of each pixel. The processing unit in each pixel consists of current-mode modules and simple logic gates. Compensation procedures are implemented in the analog modules to reduce the effect of device mismatch and charge injection. The simplicity of the circuit makes it easy to be implemented using a digital technology and integrated in detection systems.
