Parasitic extraction of MIM/MOM capacitor devices in analog/RF …
The extensive use of MIM/MOM capacitors in analog/RF designs presents parasitic extraction challenges to designers. Understanding best practices and recommended tools for extracting the complex geometries of capacitor devices, as well as the in-context coupling effects for those devices in sensitive analog/RF blocks, enables designers to accurately …
Bypass Capacitor and Coupling Capacitor: Stabilizing Voltage
Figure 1. ADP2441 switching regulator with the bypass capacitor C BYP at the input.. Because the input capacitor in a buck converter is part of the critical paths (hot loops) for this topology, C BYP has to be connected with as little parasitic inductance as possible. Thus, the placement of this component is important.
What is a Coupling Capacitor?
Coupling capacitors are useful in many types of circuits where AC signals are the desired signals to be output while DC signals are just used for providing power to certain components in the circuit but should not appear in the output. For example, a coupling capacitor normally is used in an audio circuits, such as a microphone circuit. ...

ecp audio diy: Some Notes on Coupling Capacitors
Choosing voltage is a lot easier. The voltage rating of a cap needs to be higher than any voltages that will be applied. In a solid state circuit, this is almost never a concern as most caps used for coupling are at least 200V, and usually higher (the exception to this is the use of electrolytics like Blackgates which is touched on a bit below.)
Different Types of Capacitors
Coupling capacitor, Smoothing capacitor, Decoupling capacitor. There are many other types of capacitors too that can be employed, maximum of them are discussed below: 1. Ceramic Capacitor: Ceramic capacitor is found in many appliances ranging from radio to RF. By far ceramic capacitors are the most commonly used capacitors; this is because

HFAN-01.1: Choosing AC-Coupling Capacitors | Analog Devices
When using AC-coupling in optical transceiver design, care should be taken to minimize the deterministic jitter associated with the low-frequency cutoff of the AC-coupling network. This application note discusses how to choose AC coupling capacitors that fit system requirements. Read full article.
impedance path required for optimal coupling. In contrast the impedance of a capacitor at its parallel resonant frequency (F PR) can be precipitously high. By assessing the magnitude of S21 vs. frequency for a given capacitor, excessive losses associated with F PR at the operating frequency can be readily observed. In coupling applications a ...
What are coupling and decoupling capacitors?
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.
Capacitor coupled output amplifiers | Audiokarma Home Audio …
The function of the output coupling capacitors is to keep the DC voltage from reaching the speaker. This is very common for solid state amplifiers that use a single supply rail for the output stage. The capacitance is high enough to couple all the audio frequencies to the loudspeaker. A smaller value capacitor would limit the low frequencies.
