Abstract:
1. A method of modifying a first charge packet traversing a CCD, the method comprising: establishing a potential on a first diffused region by allowing charge to flow from said first diffused region over a first potential barrier adjacent said first diffused region; maintaining a second diffused region at the same potential as said first diffused region, said second diffused region being connected to said first diffused region by a conductive path; raising the potential of said first potential barrier; lowering the potential of a second potential barrier adjacent said second diffused region; lowering the potential of said first and second diffused regions by changing a voltage on a first terminal of a capacitor whose second terminal is connected to said conductive path; transferring said first charge packet onto said first diffused region from a first CCD storage gate; sharing said first charge packet between said first and second diffused regions via said conductive path; allowing charge from said first and second diffused regions to flow over said second potential barrier to a second CCD storage gate adjacent said second potential barrier; raising the potential of said second potential barrier to its original value; lowering the potential of said first potential barrier to its original value; restoring the voltage on said first terminal of said capacitor to its original value; allowing the charge from said first and second diffused regions to flow over said first potential barrier, re-establishing the original potential on said diffused regions and disposing of the charge removed from said first charge packet.
