The use of the memristor as a programmable resistance permits the realization of memristor-based analog circuits with flexible features. This work gains some insight on memristor-based filtering applications. Adopting a PSpice implementation of the recently-introduced Boundary Condition Model (BCM) for memristive nanostructures, we analyze basic first-order low-pass and second-order band-pass memristor-based filters, whose frequency characteristics may be finely shaped through simple auxiliary programming circuitry. In particular, programming phases, dependent on some control system, respectively enable the desired modulation of the cut-off frequency and of the quality factor of the frequency response of the lowpass and of the band-pass filter. This study represents the first step towards a systematic design of memristor-based analog filters.
