Abstract
A charge-coupled device has a semiconductor body defining a charge transfer channel. Charge storage and charge transfer electrodes are provided for, respectively, defining charge wells within the charge transfer channel and transferring charge between charge wells. Two clock lines provide clock signals to the charge storage and transfer electrodes for controlling movement of charge between charge wells and to an output connection of the charge transfer channel. Signal processing means in the form of a sense amplifier are provided for processing an output from the charge transfer channel and a conductive path connects the output connection and the signal processing means. The conductive path crosses at least one of the clock lines and a conductive shielding layer extends between and is electrically isolated from the said at least one clock line and the conductive path.
