“…Several microwave components were realised using potentially printable techniques, e.g. a 2.4 GHz antenna [25], tuneable ferroelectric filters on organic substrates [26], barium strontium titanate varactors [27], all-inkjet printed capacitors [28] and ferroelectric capacitors [29]. Very fast organic PIN-diodes and rectifier circuits suited for frequencies up to 300 MHz were demonstrated [30].…”

Abstract-In this paper the recent progress of active high frequency electronics on plastic is discussed. This technology is mechanically flexible, bendable, stretchable and does not need any rigid chips. Indium Gallium Zinc Oxide (IGZO) technology is applied. At 2 V supply and gate length of 0.5 μm, the thin-film transistors (TFTs) yield a measured transit frequency of 138 MHz. Our scalable TFT compact simulation model shows good agreement with measurements. To achieve a sufficiently high yield, TFTs with gate lengths of around 5 μm are used for the circuit design. A Cherry Hopper amplifier with 3.5 MHz bandwidth, 10 dB gain and 5 mW dc power is presented. The fully integrated receiver covering a plastic foil area of 3 × 9 mm 2 includes a four stage cascode amplifier, an amplitude detector, a baseband amplifier and a filter. At a dc current of 7.2 mA and a supply of 5 V, a bandwidth of 2 -20 MHz and a gain beyond 15 dB were measured. Finally, an outlook regarding future advancements of high frequency electronics on plastic is given.

“…Ba x Sr 1-x TiO 3 (BST) thin films are receiving considerable consideration as highpotential solutions for the conception of tunable devices in the microwaves and even the millimeter-waves [1][2][3][4][5][6][7] . When integrated in capacitive metal-insulator-metal (MIM) structures, BST films are changing their permittivity upon application of a DC electric field, resulting in the modification of the overall capacitance of the MIM device with ratios up to 5:1 8 .…”

“…Indeed, the Schottky effect corresponds to an injection of charges in the dielectric by passing above the potential barrier represented by the interface 45 . In this case, the current density follows a temperature and electrical field evolution described by the equation (1). The Schottky barrier is formed because the metal work function of gold electrode (Φ Au = 5 eV) is larger than the electron affinity of the BST film (χ BST = 4.1 eV).…”

We present the conduction mechanisms of Ba 2/3 Sr 1/3 TiO 3 thin films integrated in metal-insulator-metal (MIM) capacitors and the modelling of the frequency-dependent electrostrictive resonances (in the 100 MHz-10 GHz domain) induced in the devices upon applying different voltage biases. Au/BST/Ir MIM structures on MgO substrates have been fabricated and, depending on their specific polarization, we highlighted different conduction mechanisms in the devices. Depending on the dc bias polarity, the conduction current across the material shows a space-charge-limited-current behavior under negative polarization, while under positive bias the conduction obeys an electrode-limited Schottky-type law at the Au/ BST interface. The application of an electric field on the device induces the onset of acoustic resonances related to electrostrictive phenomena in the ferroelectric material. We modeled these acoustic 2 resonances over a wide frequency range, by using a modified Lakin model which takes into account the dispersions of acoustic properties near the lower electrode/ thin film interface.

“…HIGH performance tunable filters at microwave frequency are essential components in multiband wireless communications systems. For this reason, multiple methods have been proposed to solve tunability in microwave filters, such as varactor diodes, micro‐electro‐mechanical systems (MEMS) and ferroelectric materials . However, those technologies have been struggled to fulfill the increasing demand for cost reduction, linearity and compactness.…”

In this letter, a miniaturized electrically tunable bandpass filter, based on liquid crystal (LC) technology, has been designed, manufactured and characterized through particular configuration schemes, which include low cost inverted‐microstrip structures and a dual‐mode inverted‐microstrip square loop resonator with capacitively loaded open‐loop arms. In the filter, its transitions between inverted‐microstrip and microstrip are specifically designed at the I/O ports for the self‐packaged, and its central frequency tenability is induced by applying low AC voltages for low power consumption. By measuring, the filter has a relative central frequency tuning range of 11.7% from 4.01 GHz to 4.51 GHz, and has a relative bandwidth of 13% ± 0.5% over the tuning range, a size of 28 mm × 28 mm, and an insertion loss of 1.9 and 4.5 dB at 4.01 and 4.51 GHz, respectively. © 2016 Wiley Periodicals, Inc.
