Coupling capacitors allow AC components to pass while blocking DC components. Decoupling capacitors are used in electronic circuits as energy reservoirs to prevent quick voltage changes. Bypassing capacitors clean DC signals by shunting unwanted AC components to the ground.
Coupling capacitors (or dc blocking capacitors) are use to decouple ac and dc signals so as not to disturb the quiescent point of the circuit when ac signals are injected at the input. Bypass capacitors are used to force signal currents around elements by providing a low impedance path at the frequency.
Coupling capacitors are used in analogue and digital electronic circuits. They find many applications in audio and radio frequency systems. The reactive nature of a capacitor allows it to respond to different frequencies differently. In coupling applications, a capacitor blocks low-frequency DC signals and allows high-frequency AC signals to pass.
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.
Polyester film capacitors, commonly used for coupling between two circuits. 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.
AC coupling capacitors are frequently used in multi-gigabit data links. Many current data standards require AC coupling (for example PCIe Gen 3, 10 Gb Ethernet, and so on). In addition, there exist incompatible common mode voltages between drivers and receivers, for which AC coupling is the simplest means to solve this problem.
