A novel signal integrator using CCDs
Abstract
The implementation of two types of CCD signal integrator using nonrecursive and recursive integration is described. In order to miminize the effects of transfer inefficiency, a parallel transfer scheme is employed in which information is sequentially gated into storage areas with an on chip tapped CCD register. Test devices are described that were used to investigate the proposed implementations and, in particular, the on chip addressing scheme. The results presented demonstrate the feasibility of the techniques and also show good agreement with the predicted performance. The data obtained from the test devices enabled a modified integrator to be designed, incorporating several improvements which are also described.
