Why Should a Decoupling Capacitor Be Placed Close to the IC

“Decoupling capacitors should be placed as close to the IC as possible.” Almost every electronics design textbook emphasizes this rule. However, few explain exactly why the distance matters. If this i...

Are More PCB Decoupling Capacitors Always Better?

If you have ever designed a PCB schematic, you have probably placed a familiar trio of capacitors near a chip’s power pins: 0.1 µF, 1 µF, and 10 µF.It seems like a safe bet. Different capacitance valu...

0402 vs 0603 Capacitor for High-Speed PCB Decoupling

A common misconception is that a larger capacitor package stores more energy and therefore provides better filtering performance. However, in high-speed PCB designs such as FPGA, SoC, and DDR applicat...
