A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …

In analog circuits, a coupling capacitor is used to connect two circuits such that only the AC signal from the first circuit can pass through to the next while DC is blocked. This technique helps to isolate the DC bias settings of the two coupled circuits. Capacitive coupling is also known as AC coupling and the capacitor used for the purpose is also known as a DC-blocking capacitor. A coupling capacitor''s ability to prevent a DC load from interfering with an AC source is particula…

A capacitor which is used to link one circuit''s AC signal to another circuit is referred to as a coupling capacitor. Blocking the DC signal and allowing the AC signal from one circuit to another is the main feature of this capacitor. In different circuits where AC signals are used for output, these capacitors are used, while DC signals are simply used to supply power …
A circuit diagram does not explicitly account for any coupling capacitance between conductors in a circuit. This is because coupling capacitance depends on the following aspects: ... Capacitor C2 is placed to model the pi capacitance at the input to Q1. A more accurate model would include the pin-package inductance connected to the base …
From the definition in the second function of a decoupling capacitor, the AC noise is routed to ground or bypassed to ground. Hence, decoupling capacitors are also called bypass capacitors.. In the above discussion of decoupling capacitors, we have learned how bypass capacitors route the noise to ground from power sources.
The low cost and simplicity of CWPT technology, using advanced geometric and mechanical structures of the coupling capacitors [19,20], is very useful for low-power applications, such as portable electronics devices [21], cellular phone chargers [22], and rotating machines [23]. Fig. 2 shows a typical schematic diagram of the series resonant circuit based CPWT.
