This article covers the importance of proper calibration, measurement, and de-embedding to ensure that the final capacitor model is free of errors, allowing an accurate representation of the PDN used in simulation. While capacitor models may play a seemingly minor role in the overall system design, the impact of capacitor models can significantly impact the system design and, importantly, design sign-off.

Measuring low impedance components with a 2-port vector network analyzer (VNA) is an essential technique that typically requires a VNA that costs more than $20,000. In this article, see how the authors measured an MLCC using $500 and an open-source simulation tool.

Gustavo Blando, a Samtec signal integrity architect, recently presented “DC Block Capacitor Location (Does It Matter)?” at a Samtec geEEk and spEEk webinar. Here he presents a summary of some of his key points.

The goal of power integrity (PI) analysis is to ensure not only sufficient but also stable power to all chips in a system. This article uses the example of a DDR4 application to explain the choices surrounding the use of decoupling capacitors to reduce impedance, and which performance parameters are critical to success.
