Voltage response of an active CID pixel is analyzed in detail theoretically. The linearity of the photo-response is assessed in destructive and non-destructive read-out modes of operation. The theoretical findings are illustrated by experimental data obtained from a test chip fabricated in 0.18 [micron] process. The test chip contained over 2400 active CID pixel structures with different geometries. The analysis is shown to be in good agreement with the experimental results. The charge injection device, CID25, is presented. CID25 is a color video sensor compliant with the NTSC TV standard. It has 484 by 710 displayable pixels and is capable of producing 30 frames-per-second color video. CID25 is equipped with the active pixel technology combined with parallel row processing to achieve high conversion gain and low noise bandwidth. The on-chip correlated double sampling circuitry seres to reduce the low frequency noise components. CID25 is operated by the camera system, ColoRAD, consisting of two parts, the head assembly and the camera control unit. These two parts are separated by a cable that can be up to 150 meter long. The CID25 imager and the head portion of the camera are radiation hardened. They can produce color video with insignificant signal-to-noise ratio degradation out to at least 4 Mrad of total dose of ⁶⁰Co [gamma]- radiation. Detailed results of ColoRAD system testing before, during, and after irradiation are presented and discussed. In summary ColoRAD is the first radiation hardened color video system, based on a semiconductor photo-detector that has an adequate sensitivity for operation in room lighting environments
