Abstract
Novel readout and support-circuit concepts in a CMOS imager are described for the replacement of conventional silicon photodiodes in applications requiring bandwidths of 1 MHz and more. Conventional silicon photodiodes are the detector of choice for high-speed applications but have been replaced by CCD arrays and CMOS imagers when spatial resolution is needed. These imagers can be comparable to photodiodes in responsivity and generally have the advantages of lower noise, low cost, compatibility with 'system-on-a-chip architectures and the ensuing low power and low cost. For space applications, the CMOS devices are highly tolerant of ionizing radiation. With a novel readout architecture and suitable digital and analog support circuitry on- chip, a CMOS imager concept has been identified to replace conventional photodiodes in some important niche applications.
