By means of thin film technology a reduction of size, cost, and power consumption of electronic circuits can be achieved. The required specifications are attained by proper design and combinations of innovative materials and manufacturing technologies. This thesis focuses on the development and fabrication of low-loss ceramic thin film devices for radio and microwave frequency applications. The...

the well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. a new model that was previously proposed by the authors that combines a mass with a pulley (mp) is shown to simulat...

A novel fishbone-shape parallel-plate-based capacitor with high tunability and linear C-V response is presented. The electrodes consist of a set of lateral cantilever beams of different lengths, attached to a longitudinal fixed-fixed beam. An insulating layer prevents contact between the electrodes. When a DC voltage is applied, the longitudinal and lateral beams undergo out-of-plane deformatio...

An error cancellation technique is described for suppressing capacitor mismatch in a successive approximation A/D converter. At the cost of a 50% increase in the conversion time, the first-order capacitor mismatch error is cancelled. Methods for achieving top-plate parasitic insensitive operation are described, and the use of a gain-and offset-compensated opamp is explained. SWIT-CAP simulation...

This paper presents the application of model-based and data-driven approaches for prognostics of failures in embedded planar capacitors. An embedded planar capacitor is a thin laminate that serves both as a power/ground plane and as a parallel plate capacitor in a multilayered printed wiring board. These capacitors have gained importance with an increase in the operating frequency and a decreas...

Future microwave networks require miniature high-performance tunable elements such as switches, inductors, and capacitors. In this paper, high performance variable capacitor was fabricated by simple microelectromechanical systems (MEMS) technology. The capacitance and quality (Q) factor at 1 GHz are 0.792 pF and 51.6. The pull-in voltage is 13.5 V and the tuning ratio of the capacitor is more t...

An analytical model based on an equivalent capacitance circuit for expressing a static effective permittivity of a composite dielectric with complex-shaped inclusions is presented. The dielectric constant of 0–3 composites is investigated using this model. The geometry of the capacitor containing a composite dielectric is discretized into partial parallel-plate capacitor elements, and the effec...

The challenge in using fully mechanized caving mining technology for thick coal seam is monitoring the mixing ratio of gangue during top process. In this paper, we propose a passive wireless sensing system based on second-order parity-time symmetric operated around exceptional point mixing, which has an LC resonance structure consisting spiral resonant coil and parallel-plate capacitor at end s...

Transparent Conductive Oxides (TCOs) are a class of materials with high optical transparency and electrical conductivity. This combination makes them extremely appealing for solar cells, optoelectronics infrared-plasmonics applications. In this work, we report the active tuning response aluminium-doped ZnO (AZO) films upon gating within parallel-plate capacitor configuration. We investigated el...
