Abstract
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 Φthat require nearly two times less swing to achieve same effect.
