How to choose the best capacitors for power supply filtering?
To start selecting the best capacitors for power supply filtering, you need to get into a capacitor datasheet and delve through some specifications. Some of the important specifications are as follows: Capacitor material: Your capacitor might be a ceramic, electrolytic, tantalum, polyester, or other material.
What is a flying capacitor in an active filter circuit?

How does a capacitive filter work?
A capacitive filter smooths additional pulses in the output stage so that an almost constant DC voltage is supplied to the load.
