We asked for you to send in your questions for Happy Holden, and you took us up on it! The questions you've posed run the gamut, covering technology, the worldwide fab market, and everything in between. Enjoy.
Q: How important are GND reference planes in signals that are less than 50MHz, since 1/4 wavelength is about 30 inches?
A: GND is an essential part of the circuit. The return path for DC is the lowest resistance, but for the AC part of the signal, it is the lowest inductance.
Take the survey to pose your own question for Happy Holden.

Study on Resonance Mitigation in Metallic Shielding for Integrated Circuits
07/08/2025 | Article by Maria Cuesta Martin, Victor Martinez, Vidal Gonzalez Aguado, Würth ElektronikInherent cavity resonant modes often lead to significant degradation of shielding effectiveness, responsible for unwanted electromagnetic coupling. Cavity resonant modes of the metal shielding enclosure can produce two adverse problems: the mutual coupling among different RF modules and shielding effectiveness reduction of the metal enclosure. The cabinets serve to shield certain components from electromagnetic interference (EMI). However, these cavities present some resonance peaks at 5 GHz, making it impossible to use them at higher frequencies.
