“…In 2008, Prof. Chua's theoretical concept of memristor [1] became a reality when Strukov et al published their studies on the relationship between magnetic flux and charge in a TiO 2 -based two compact terminal device for the first time [2], which has triggered the interests of researchers around the globe. Apart from various potential applications ranging from logic operations and reconfigurable radio frequency systems to non-volatile memory applications [2][3][4], memristors have also been investigated to emulate the bio-synaptic functions because of their similar structure and working dynamics. Nowadays, it is widely accepted that direct emulation of synaptic functions in an electronic device is crucial for the development of brain-inspired neuromorphic computing systems [5][6][7].…”

In this study, by inserting a buffer layer of TiO x between the SiO x :Ag layer and the bottom electrode, we have developed a memristor device with a simple structure of Ag/SiO x :Ag/TiO x /p ++ -Si by a physical vapor deposition process, in which the filament growth and rupture can be efficiently controlled during analog switching. The synaptic characteristics of the memristor device with a wide range of resistance change for weight modulation by implementing positive or negative pulse trains have been investigated extensively. Several learning and memory functions have been achieved simultaneously, including potentiation/depression, paired-pulse-facilitation (PPF), short-term plasticity (STP), and STP-to-LTP (long-term plasticity) transition controlled by repeating pulses more than a rehearsal operation, and spike-time-dependent-plasticity (STDP) as well. Based on the analysis of logarithmic I-V characteristics, it has been found that the controlled evolution/dissolution of conductive Ag-filaments across the dielectric layers can improve the performance of the testing memristor device.

This paper presents a compact multifunctional reconfigurable filter based on double coupled‐line structures with three different filtering modes. Three different working modes of the wideband bandpass filter (BPF), bandstop filter (BSF) and wideband filter with single notch can be switched. One prototype of the reconfigurable filter is constructed and measured. For the wideband BPF mode, the 3‐dB bandwidth is 84.5%with in‐band return loss (RL) higher than 21.5 dB and minimum insertion losses (IL) of 0.9 dB, and rejections for the upper stopband is higher than 22.5 dB. For the wideband filter with single notch mode, the 3‐dB bandwidth is 39.7% and 24.9%, with the minimum in‐band IL of 1.13 dB and 1.5 dB, respectively. The maximum rejections between the two bands are 32 dB, and the upper stop band rejections are higher than 19 dB. For the BSF mode, the 3‐dB bandwidth is 29.6%.

“…Furthermore, dual-mode BPFs using surface integrated waveguide (SIW) resonator structures have been reported in the literature (Zhang et al , 2010; Liu et al , 2016; Chaudhury et al , 2018; Muchhal and Srivastava, 2019) with high-selectivity. Also, reconfigurable dual-mode BPFs based on memristor switch (Potrebic´ et al , 2018) and varactor-tuning (Guo et al , 2018) were demonstrated with a larger circuit size. Various fractal resonator structures (Mezaal et al , 2015; Lu et al , 2017; Feng, 2018; Karthie and Salivahanan, 2019) have also been explored for the design of dual-mode BPFs with narrow fractional bandwidths (FBWs).…”

Purpose The purpose of this paper is to present the design of a compact microstrip bandpass filter (BPF) in dual-mode configuration loaded with cross-loop and square ring slots on a square patch resonator for C-band applications. Design/methodology/approach In the proposed design, the dual-mode response for the filter is realized with two transmission zeros (TZs) by the insertion of a perturbation element at the diagonal corner of the square patch resonator with orthogonal feed lines. Such TZs at the edges of the passband result in better selectivity for the proposed BPF. Moreover, the cross-loop and square ring slots are etched on a square patch resonator to obtain a miniaturized BPF. Findings The proposed dual-mode microstrip filter fabricated in RT/duroid 6010 substrate using PCB technology has a measured minimum insertion loss of 1.8 dB and return loss better than 24.5 dB with a fractional bandwidth (FBW) of 6.9%. A compact size of 7.35 × 7.35 mm2 is achieved for the slotted patch resonator-based dual-mode BPF at the center frequency of 4.76 GHz. As compared with the conventional square patch resonator, a size reduction of 61% is achieved with the proposed slotted design. The feasibility of the filter design is confirmed by the good agreement between the measured and simulated responses. The performance of the proposed filter structure is compared with other dual-mode filter works. Originality/value In the proposed work, a compact dual-mode BPF is reported with slotted structures. The conventional square patch resonator is deployed with cross-loop and square ring slots to design a dual-mode filter with a square perturbation element at its diagonal corner. The proposed filter exhibits compact size and favorable performance compared to other dual-mode filter works reported in literature. The aforementioned design of the dual-mode BPF at 4.76 GHz is suitable for applications in the lower part of the C-band.
