ABSTRACT:
A charge coupled device transfers a charge via a meandering route in a channel having at least one bend. The selected channel bending angle has a maximum of two right angles, or 180.degree.. When the channel bending angle is less than 180.degree., the channel may be formed into a ring by being bent a plurality of times. The gate electrode is of simple rectangular form, and is bent at the same angle as the channel where the channel is bent. If the channel is bent at 180.degree., a signal injected from an input end is transferred to an area adjacent to the input end. The signal may be injected again at the input end for circulation, after amplification.
