128 Mb/s multiport CMOS binary active-pixel image sensor

Abstract

A 128/spl times/128 photo-diode active pixel sensor (APS) with an on-chip array sequencing controller and 1b thresholding circuitry processes 8,192-frames/s at a 128 Mb data rate onto a 8 b wide parallel-digital output port. In addition, the on-chip controller can be commanded to output data through either a serial digital port for lower bandwidth requirements or through a serial analog port for higher-resolution off-chip analog-to-digital conversion.
