Abstract :
An analog module for processing a fax scanner´s signals is presented. The module is a section of a complete solution fax system chip, which utilizes current mode CMOS circuits in a noisy environment to produce an 8-b resolution, 64 gray-level pictures from a low-cost (low performance) charge coupled device (CCD), or contact-type image sensor (CIS) scanners
