Decoupling Capacitor Value Determining the Circuit Capacitance for Signal Stabilization

Decoupling Capacitor Optimization to Achieve Target Impedance in PCB PDN Design Abstract: With increasingly stringent requirements for lower voltage supply, and higher density in PCB (Printed Circuit) PDN (Power Distribution Network) design, power integrity has an increasingly important role in PCB design. The PI performance of the PCB design must meet requirements, or modification and trial.


Electronic IC decoupling capacitor design Valuable Tech Notes

Power supply noise management continues to be a challenge with the scaling of CMOS technologies. Use of on-chip decoupling capacitors (decaps) is the most common noise suppression technique and has significant associated area and leakage costs. There are numerous methods of implementing decaps and it is not always clear which implementation is the most optimal for the given design constraints.

First, consider decoupling capacitors. It is generally stated that the purpose of PCB decoupling capacitor placement is to ensure the voltage between the power rail/plane and the ground plane remains constant against low-frequency power supply noise, ringing on the PDN, and any other voltage fluctuations on the PDN.

With the ever-increasing integration density of electronic systems and reduced noise margins, maintaining high power integrity has become a formidable challenge in the design of high-performance 3D integrated circuits (3D ICs). To enhance power integrity, the insertion of decoupling capacitors has proven to be an important and effective solution. However, existing decoupling capacitor.


Decoupling Capacitor Placement Guidelines for PCB Design

Decoupling capacitors help to isolate, or de-couple, local circuits from noise and power anomalies from other devices on shared power, ground, and other nets. They are typically applied to power sources to provide a localized source of instantaneous current and provide isolation of the local circuit from power noise in other areas of the design.

In electronics, a decoupling capacitor is a capacitor used to decouple (i.e. prevent electrical energy from transferring to) one part of a circuit from another. Noise caused by other circuit elements is shunted through the capacitor, reducing its effect on the rest of the circuit.

Decoupling capacitors are used for power supply and transient decoupling because of their intrinsic energy storage capability. Complex PCB assemblies have multiple power supplies that require voltage regulation to ensure the proper operation of components such as processors, FPGAs, ICs, or amplifiers.

ABSTRACT Much research has been done on decoupling capacitor selection and placement for BGAs. This application report provides the current best practices, and what TI recommends in general for placement and selection of values. In the past, TI (and many other semiconductor companies) recommended 1 capacitor (cap) per power pin.
