Abstract
A charge coupled device has a meandering charge path formed by a channel stop of unique shape. The channel stop is of interdigitated pattern, and the gate electrodes form a straight strip. The channel stop pattern and an asymmetric depletion layer formed within the channel cause the transfer of the charge through the channel via the meandering charge path. A transversal filter and imaging device are readily provided by extracting the signal from one or both sides of the channel.
