A CCD serial to parallel shift register

Charge-coupled devices have been well known for their serial-type applications. The authors report a new scheme whereby parallel outputs can be obtained from every bit of a serial CCD shift register without destroying the transferred charge and without the use of an external resetting pulse. The results of a 20-b 3/spl phi/ CCD shift register with parallel outputs are described. The work extends the applicability of CCD's to a less restricted area.
