Abstract
In this thesis I shall introduce the use of a pseudo-memcapacitor as a possible replacement of a standard capacitor in a buck-converter circuit, demonstrating that it can decrease the output ripple in case of an increase of the load resistance. In the first part, the necessary theory about the memristor and memcapacitor for devel- oping the pseudo-memcapacitor model will be described. In the second part, the main simulation program, LTSpice®, and the components/instrumentation for the hardware emulation of the final schematics will be analyzed. In the third part I will develop the several models that allow to create a pseudo-memcapacitor device starting with (and also modifying) the memristor and memcapacitor models with the relative simulations. In addition, i will simulate the buck-converter schematics with the pseudo-memcapacitor model included, and i will design a circuit with discrete components able to emulate it.È consentito all'utente scaricare e condividere i documenti disponibili a testo pieno in UNITESI UNIPV nel rispetto della licenza Creative Commons del tipo CC BY NC ND.
