Abstract

A modulation device includes at least one memristive device, and a control block, the modulation device having an equivalent conductance yi(t) produced by the at least one memristive device and the control block being configured to receive a clock signal and perform a first modification of the equivalent conductance yi(t) upon receipt of each clock signal, receive an input voltage pulse and perform a second modification of the equivalent conductance yi(t) upon receipt of each input voltage pulse, the first and second modifications being in opposite directions.
