A device and method for continuous vertical clocking a charge-coupled device image sensor operating in a time delay and integration and binning mode of operation is disclosed. The method includes providing a charge-coupled device image sensor with a continuous charge transfer signal to a vertical charge-coupled device register for shifting charge continuously to more closely approximate the speed of movement of the target object of capture by the image sensor in order to eliminate artifacts in the TDI imaging direction. The control module of the CCD image sensor provides the continuous charge transfer signal to the vertical charge-coupled device register.

Continuous clocking mode for TDI binning operation of CCD image sensor

A charge multiplication amplifier device comprises a series arrangement of a first separation barrier facility, a temporary storage well for charge carriers, a second charge transfer barrier facility, an impact ionization facility that is operative through electric field strength effective on mobile charge carriers, and a charge collection well for receiving charge carriers so multiplied. Advantageously, the device comprises a charge collection and transfer facility () that is geometrically disposed next to the impact ionization facility () whereas impact ionization facility is controlled at a substantially static electric potential (DCDC) for controlling the electric field strength. Advantageously, another embodiment of this device comprises charge collection and transfer facilities () implemented as two (or more) independently clocked signals &#x3a6;that require nearly two times less swing to achieve same effect.
