What is floating capacitor?

A floating capacitor is a type of capacitor that is not connected to a fixed reference point, such as ground or a power supply, allowing it to maintain a potential difference independently. This can be useful in various applications, such as in analog circuits where isolation from other components is required. Floating capacitors can help in reducing noise and improving circuit performance by preventing ground loops. They are often used in applications like signal coupling, filtering, and energy storage.
