Main-line memristor mounted type loaded-line phase shifter realization

In this paper, we present a possible application of memristive switches for implementation of main-line mounted loaded-line phase shifters. The underlining idea is to replace PIN diodes, acting as RF/microwave switches, with memristors in order to reduce power consumption. As a proof-of-concept, circuit-level simulations are performed to validate the expected functionality. Parasitic effects caused by the memristor programming circuitry, which might be relevant at RF/microwave frequencies, are taken into consideration. Pi's model is used to represent memristors at RF/microwave frequencies and Biolek's model is used for exploring the memristance setting issues. Our simulation results make memristors the promising candidates for the phase shifters. (C) 2017 Elsevier B.V. All rights reserved.
