Abstract: An analog-to-digital circuit that digitizes an analog voltage. The analog-to-digital circuit includes plural comparators functionally connected to form a tree that has levels i, and each level i has branches j, and an encoder connected to the plural comparators and configured to generate a digitized value of an input analog voltage. Each comparator from a level i has first and second outputs, and each of the first and second outputs is electrically connected to an input of different comparators from a next level i+1 of the tree.

Abstract: A mechanical resonator-based cascadable logic device includes which includes a resonator having a beam with a first fixed end, a second fixed end, and a length between the first and second fixed ends. A first electrode and a second electrode are aligned along a first side of the beam. A third electrode and a fourth electrode are aligned along a second side of the beam and opposite the first and second electrodes. A DC voltage source is coupled to one of the first and second fixed ends of the beam. At least one of the first, second, third, and fourth electrodes is coupled to a first AC voltage source so that a logic operation is performed by activating a second resonant mode of the resonator.
