Multiplication register for amplifying signal charge

Abstract From the Canadian patent

A multiplication register for use in solid state imaging apparatus, such as a CCD, is described. The multiplication register has a gain element comprising a plurality of register electrodes, for transferring charge along a charge transfer channel and for , amplifying the charge. Channel edge defining electrodes are disposed either side of the channel in , place of channel stops, removing the effects of spurious charges generated in the channel in the regions of amplification. The provision of the channel edge defining electrodes allows the resulting structure of the channel electrodes to be made simpler, and means that a structure can be provided for clocking and amplifying …
