Abstract

The modeling and design of a BJT-based silicon retina for image smoothing and edge detection is presented. The resistor in the network of the silicon retina is implemented by the base spreading resistance of BJTs. The outputs are taken from the emitters of BJTs. Due to the debias effect among the emitters of BJTs, this network presents a smooth function like the horizontal cells in a real retina. This network can be easily implemented in standard CMOS technology, with a very compact structure
