A novel chip implementing random scan was designed, fabricated, and tested. The chip covers the basic requirements for random access and separation between the sampling and reading processes. In this way, a repeated reading of any pixel at any time can take place. The chip includes an 80 × 80 matrix of basic cells. Each cell consists of two stages: The first is based on a switch, whereas the second includes a buffer. The chip was fabricated in a 3-pm CMOS process. It was found to operate functionally. However, the use of a standard process gave rise to the crosstalk phenomenon, which has yet to be overcome.
