Abstract
In one example, an oxide-based negative differential resistance comparator circuit includes a composite NDR device that includes a first electrode, a first thin film oxide-based negative differential resistance (NDR) layer in contact with the first electrode and a central conductive portion. The composite NDR device also includes a second thin film oxide-based NDR layer disposed adjacent to the first NDR layer and a second electrode. A resistor may be placed in series with the composite NDR device and an electrical energy source can apply applying a voltage across the first electrode and second electrode. The composite NDR device produces a threshold based comparator functionality in the comparator circuit.
