Abstract:
A metal-insulator-metal layered structure is disclosed which is useful as a rectifier of AC voltage. One of the metal layers is advantageously in the form of a crossgrid-type geometry, in order to afford a large perimeter of contact with the insulator layer. Electrons are injected at the edges of the metal grid through the insulator when the grid goes electrically negative, but not when it goes positive; thereby, rectifying properties are afforded by this metal-insulator-metal structure.
Abstract:
The invention is a form of monolithic semiconductor apparatus adapted for the storage and manipulation of electronic signals representing information. Basically, the apparatus includes a plurality of spaced localized zones of one type semiconductivity adjacent the surface of a semiconductive bulk portion of the other type conductivity. A plurality of localized electrodes, registered in one-to-one correspondence with the localized zones, are disposed over a dielectric layer covering the semiconductive portions. Each of the electrodes is delimited in lateral extent so as to extend over substantially all of the space between a pair of closest zones and over a substantial portion of only one of that pair of zones so that the capacitance between the electrode and the zone over which it extends is substantially greater than the capacitance between that electrode and the other zone of that pair of zones. Signals in the form of varying deficiencies of majority carriers are stored temporarily in the localized zones and are gated sequentially from one zone to the zone next adjacent upon application of two-phase clock pulses to alternate electrodes. Constant background pulses upon which signals are superimposed are circulated to reduce distortion.
Abstract:
Apparatus and method for converting between series and parallel data streams. In a charge transfer device (CTD) shift register having 2M (M is an integer greater than one) parallel registers each having an input node and an output node, a CTD input logic tree connects all the input nodes to a single data input node, and a CTD output logic tree connects all the output nodes to a single data output node. The input logic tree successively splits up an input data stream into two data streams until the number of data streams is 2M and the output logic tree successively combines data streams from each output node two at a time until a single output data stream is achieved.
