Abstract
A multiplication register for use in solid state imaging apparatus, such as a CCD, is described. The multiplication register has a gain elementcomprising a plurality of register electrodes, and, for transferring charge along a change transfer channel, and for amplifying the charge. Channel edge defining electrodesandare 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 electrodesandallows the resulting structure of the channel electrodes to be made simpler, and means that a structure can be provided for clocking and amplifying charge in either direction along the channel.
