Millibels in the Wind

Voiceless it cries, Wingless flutters, Toothless bites, Mouthless mutters. Radiometers are cool. Some are so cool they are cryogenically cool. They have to be really cool to do what they do. This is especia... Read More...

Resistor Value for Measuring Leakage Current

Furor and controversy are words which describe the process by which standards committees decide the value of the resistor in the leakage current measuring network. However, the different specified resistor values create no more than a 6.25% error for the value of the leakage current.

Things You May Not Have Heard About Shielding

What determines how effective a cable shield is going to be? And how does the decision to ground or not ground a shield impact its effectiveness? Fortunately, there is a well-developed theory of shielding, which will be discussed as a way to get a general understanding of what can be expected of shield performance. But there’s more to it.

EU-US Transatlantic Trade and Investment Partnership

1406 F2 coverCan thousands of regulations be harmonized?

Last summer, the European Union (EU) and the US took the first steps to establish a partnership between the two markets that together account for almost half the world’s economy. Teams of negotiators met in Washington to talk about how best to take the Transatlantic Trade and Investment Partnership (TTIP) forward, and even though the second round of negotiations was canceled due to pressing political issues, both sides expressed a firm commitment to the TTIP process.

Differential Mode to Common Mode Conversion on Differential Signal Vias Due to Asymmetric GND Via Configurations

1406 F3 coverThis article investigates the impact of ground vias placed in close proximity to high speed differential signal vias and the resulting differential mode to common mode conversion. The work shows the influence of the distance between ground (GND) vias and differential signal (Diff. SIG.); the effect of the asymmetrical configuration of the GND vias; the impact of the dielectric thickness and the number of transitions between the planes.

The “Real” Cost of ESD Damage

1406 F4 coverAnyone who has worked in quality or reliability in a large corporation knows that developing and presenting credible failure cost information can be difficult. This is particularly true for ESD, where the events and their effects are invisible and not nearly as well understood as other more obvious classes of failure, such as mechanical or contamination.
