Abstract:

Considerations About Controlled CapacitorsA new type of thermal controlled capacitor has been developed and studied. The capacitor non-linearity depends on the control parameter — temperature. At constant temperatures, the charge versus voltage curve is non-linear and has thermal inertia. Actually, it is a new method to modify the capacitors' capacitance using the thermal field as a command parameter and brings new technical solutions for protection of electrical equipment.

Abstract:

Electronics Practicum in the Laboratory is a routine activity carried out to support student skills. Capacitors are one of the components that are often used in practice. Capacitors are one of the passive electronic components that have a magnitude value in the form of capacitance in Farad units. The capacitance value indicates the capacitor's ability to store electric charge. However, the value contained on the capacitor label is not necessarily the actual value because the capacitor has a tolerance range. Of course, this is very influential in the measurement and performance of electronic ci

Many recent studies have revealed that PoL (Point of Load) converters’ output capacitors are a paramount component from a reliability point of view. To receive the maximum degree of reliability in many applications, designers are often advised to derate this capacitor—as such, a careful comprehending of it is required to determine the converter’s overall parameters. PoL converters are commonly found in many electronic systems. Their most important requirements are a stable output voltage with load current variation, good temperature stability, low output ripple voltage, and high efficiency and

Abstract:

In order to reduce die size and increase capacity, the metal-insulator-metal (MIM) capacitor area in circuit designs fabricated using GaAs hetero-junction bipolar transistor (HBT) technology has to be reduced. This can be achieved by using a capacitor dielectric material that has a high dielectric constant or high capacitance density. In GaAs HBT technology, the MIM capacitor dielectric film is typically also required to have a high breakdown voltage (>20 V) and low leakage current. Furthermore, the deposited dielectric film has to be compatible with GaAs processing and has to be deposited

Abstract:

The compensation capacitor fault of jointless track circuit has an important impact on the safe operation of high-speed trains. In order to solve the problem of multiple compensation capacitors breaking at the same time in jointless track circuit, a fault diagnosis method based on the amplitude characteristics of induced voltage envelope curve is proposed. Firstly, the shunt state model of track circuit is established, and the envelope curves of induced voltage amplitude corresponding to the disconnection fault of compensation capacitors at different positions are obtained by simulating analys

Abstract:

In this work, we investigated applicability of boron nitride (BN) and boron oxynitride (BNO) thin films to fabricate multilayer ceramic capacitors (MLCCs) for high temperature and high frequency applications. Advantages of BN include high temperature and chemical resistance, which should result in more compact and reliable devices. Deposited BN layers by a filamentless ion source assisted physical vapor deposition technique show a high thermal stability up to 1000 °C and a very high breakdown voltage of about 600 V/μm. A 15 mm × 15 mm capacitor geometry was picked to create a simpler packaging

This paper presents an analysis on the parasitic capacitors effect of the fully differential architecture to provide common-mode rejection. The parasitic capacitors of differential comparator inputs has no effect on the resolution, however, the difference of comparator input parasitic capacitors may has great effect on the resolution. The relationship between the unity capacitor and the parasitic capacitors of the differential comparator inputs is analyzed by giving precise theoretical demonstration. Therefore, a theoretical basis is provided for designers to choose appropriate unity capacitor

Power capacitors of high-voltage alternating/direct current transmission systems have become one of the main community noise sources because of their large number and because they employ ultrahigh voltage and power.

Abstract:

A new fundamental principle of the theory of dielectrics in capacitors is demonstrated. That is, dielectric material in any geometry that reduces the field generated by charges on capacitor electrodes is effective in increasing capacitance. Specifically, it is shown that super dielectric material on the outer surfaces of the electrodes of a parallel plate capacitor increases dielectric constant, as well as energy and power densities, by orders of magnitude. The implicit assumption in all current capacitor theory, that the “capacitor” is only that region occupied by the electrodes and the space

To embed high value capacitors (&gt;20nF), a high K (over 500) material which can be co-fired with low K LTCC was developed successfully. Thin high K sheets under 10μm were co-laminated between low K sheets, which form the power and ground planes. Due to the short distance from the IC power pin to the decoupling capacitor, the ESL (Equivalent Series Inductance) is much lower than with surface mounted type capacitors, and so, SSN (Simultaneous Switching N
