Bypass Capacitor Used in PCB Circuit Board Gerber File Rerouting

Bypass capacitor is playing an important role in the PCB circuit board gerber file rerouting, the bypass capacitors can be placed in the following two positions on the pcb circuit board gerber file: one capacitor (10µF to 100µF) is placed on the power supply side, and the other capacitor is placed next to each active device (including digital and analog devices).

The value of the bypass capacitor added to the device depends on the device used. If the bandwidth of the device is less than or equal to 1MHz, a 1µF capacitor can significantly reduce the noise introduced.

If the bandwidth of the device is greater than 10MHz, a 0.1µF capacitor may be appropriate. If the bandwidth is between these two frequencies, you can use the two capacitors at the same time, or use one of them.
