What is a coupling capacitor?
AC circuits use DC as input and AC as the output. The circuit output can be interfaced with a capacitor with a load called the coupling capacitor. But selecting suitable capacitance depending on the signal frequency is significant, but the resistance must connect in parallel with the capacitor.
What is the difference between a coupling capacitor and a decoupling capacitor?
Coupling capacitors are mainly used in analog circuits whereas the decoupling capacitors are used in digital circuits. The connection of this capacitor can be done in series with the load for AC coupling. A capacitor blocks low-frequency signals like DC and allows high-frequency signals like AC.
Why are coupling capacitors preferred in digital circuits?
Hence coupling capacitors are preferred in analog circuits. In the case of decoupling capacitors, these are preferred in digital circuits. The coupling capacitor, generally only allows the AC signal to be transmitted from one circuit to another. Let us see how it happens.
Are decoupling capacitors preferred in digital circuits?
There exist decoupling capacitors as well in which the output generated is consisting of DC signals. Hence coupling capacitors are preferred in analog circuits. In the case of decoupling capacitors, these are preferred in digital circuits. The coupling capacitor, generally only allows the AC signal to be transmitted from one circuit to another.
What is an example of a parallel capacitor?
One example are DC supplies which sometimes use several parallel capacitors in order to better filter the output signal and eliminate the AC ripple. By using this approach, it is possible to use smaller capacitors that have superior ripple characteristics while obtaining higher capacitance values.
How to choose a capacitor for coupling Applications?
Whenever a capacitor is selected for coupling applications, there are some key parameters that need to consider like series resonant frequency, impedance, and equivalent series resistance. The value of the capacitance mainly depends on the frequency range of the application & the impedance of load or source.
