Abstract : A field emitter array comparator is provided wherein voltage or current input signals supplied to at least two deflectors control the selective deflection of a beam of electrons to one collector of a collector array of at least two collectors. The beam of electrons is generated by a source of electrons, such as a field emitter array, in an evacuated chamber, and the at least two deflectors are disposed in preselected positions relative to the electron source. The input signals to the at least two deflectors cause deflection of the beam of electrons in the direction of the deflector to which the most positive signal is applied, thus causing the electron beam to strike a collector positioned in the path of the deflected beam. This results in a reduction in voltage associated with that collector. In general, the voltages on the collectors are used to determine whether the signal inputs are equal or, if unequal, which input has the greatest magnitude. Patent Applications. (RRH)
