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.
3. Bypass Capacitors: Definition and Function: Bypass capacitors provide a low-impedance path for high-frequency noise, effectively bypassing it to the ground. They are placed parallel to the power supply line and the ground to divert high-frequency noise away from the sensitive components.
This is because they are shunted to the ground sometimes. Some of the few noticeable difference between the bypass capacitor and decoupling capacitors are , the bypass capacitor is designed to shunt the noise signals where as the decoupling capacitors are designed to smoothen the signal by stabilizing the distorted signal.
Coupling Capacitors: Transfer AC signals between stages while blocking DC. Decoupling Capacitors: Stabilize the power supply by filtering out noise and voltage fluctuations. Bypass Capacitors: Provide a low-impedance path for high-frequency noise to ground. Coupling Capacitors: Between circuit stages.
The use of an output coupling capacitor (C 2) is illustrated in Fig. 6-2 (c). Like the input coupling capacitor, C 2 offers a dc open circuit and behaves as an ac short-circuit. Thus, it passes the output waveform to the load without affecting the circuit bias conditions.
However, there are applications in which decoupling with a bypass capacitor is only possible on the bottom side of the board. One example is when there is not enough space for a large decoupling capacitor. In such cases, vias are used to connect the capacitor. Unfortunately, they have a few nanohenries of parasitic inductance.
