A method for processing input variables using a processing device having at least a first transistor, for example a field-effect transistor. The method includes: providing the first transistor and a first memristive circuit device which characterizes a first input variable associated with the first transistor, wherein a charging current of a capacitor associated with a control electrode of the first transistor can be influenced by means of the first memristive element; applying to the control electrode of the first transistor a first control signal which characterizes a second input variable associated with the first transistor and which has at least periodically a non-constant amplitude; ascertaining a first output variable on the basis of a first variable characterizing a time curve of a current through a load path of the first transistor.

An apparatus. The apparatus includes at least a first comparator device, which is designed to compare a first input current with a first reference current and, based on the comparison, to output a first output current to a second comparator device, wherein the first output current corresponds to a difference of the first reference current and the first input current if the first input current is smaller than the first reference current, and wherein the first output current corresponds to a difference of the first input current and the first reference current if the first input current is greater than or equal to the first reference current.
