Abstract
CCD methods and devices for recording transient data signals, in which charge is transferred under the influence of transmission line fields at sampling sites disposed along a charge transfer channel.
Claims12
An integrated circuit device for recording transient data signals comprising,
- charge transfer channel means for providing a plurality of charge potential wells at a plurality of sampling sites disposed along a charge transfer channel, and for transferring charge carrier packets along said channel,
- an electrical transient data signal transmission line means disposed at least in part along said transfer channel means at said sampling sites, for receiving an electrical transient data signal to be recorded and for propagating said electrical transient data signal successively to each of said plurality of sampling sites such that said electrical transient data signal propagated thereon is distributed along said transmission line means to apply the electric field of said transient data signal distributed thereon to charge carriers at each respective sampling site, and
- means for transferring and isolating charge carriers at a selected sampling time when a transient data signal to be recorded is distributed along said transmission line at each of said charge potential wells in response to the transient data signal potential provided by said transmission line means at each of said respective sampling sites to thereby provide charge packets of charge carriers disposed along said charge transfer channel which record said electrical transient data signal.
A method for recording transient data signals comprising the steps of
- providing a plurality of charge potential wells at a plurality of sampling sites disposed along a charge transfer channel,
- propagating a transient electrical data signal to be recorded along an electrical transmission line sequentially to each of said plurality of sampling sites to distribute the transient data electrical data signal along the respective sampling sites such that the electric field potential of the distributed transient data signal is applied to each respective sampling site such that a representation of the electric field of the transient data signal in time is provided along said sampling sites, transferring charge carriers at a selected sampling time at each of said charge potential wells under the influence of said respective transient data signal electrical fields at each of said sampling sites to provide analog charge packets of charge carriers respectively at each sampling site representative of the electric field of the transient data signal at each such site at said respective sampling time, and
- isolating said analog charge packets to provide an analog record of said transient data signal.
