摘要： An electron beam analog to digital converter wherein an input signal to be quantized is applied to the deflection circuitry of an electron beam generation device where the electron beam is made to sweep an angle proportional to the amplitude of the input signal in a first orthogonal direction (horizontal) across a linear array of detector elements which generates an output signal at the angle of deflection. A sinusoidal reference signal is simultaneously applied to a second set of deflection plates which causes electron beam to sweep in a second orthogonal direction (vertical) whereupon the deflected electron beam periodically sweeps across the detector array and a time sample of the output voltage is generated during a crossover interval. The detection voltage is then converted to an output signal having a binary value corresponding to the amplitude of the analog input signal.

摘要： An analog to digital converter for high-speed, high-accuracy conversion includes a charge storage means for storing an input analog value to be converted, means for controlling discharge of the charge storage means, a comparator means for sensing discharge level of said charge storage means and transmitting a stop signal at a precise time, a tapped delay line means which is responsive to a start signal to generate a sequence of binary values, a first register means responsive to the stop signal for capturing the binary values corresponding to a delay time between the start and the stop signal, and an encoder means coupled to the register means for converting the binary values to a digital value representative of the input analog value. In a further embodiment, a counter means and a second register means are employed in parallel with the tapped delay line means and the first register means in connection with a frequency reference to provide digital conversion over a wide dynamic range, the first register means and the tapped delay line means capturing input binary values over at least one cycle of the frequency reference which is one count of the counter.

摘要： RF field is sensed to produce an incoming voltage that drives a microarray of electron guns in a sweep pattern towards a detector array. The electron guns emit a beam current that may amplify the incoming voltage signal, and the detector material may be selected to amplify the beam current at the detector, for example, by avalanche and/or cascade in a Schottky material, to provide a low current, high gain amplification. The microarrays may be arranged in various combinations to produce successive amplifications, frequency multipliers, transmit-receive amplifiers, crossbar switches, mixers, beamformers, and selective polarization devices, among other such devices.
