The basic design rules for power distribution networks (PDN) teach us that the best performance is obtained from a uniform, frequency independent (or flat) impedance profile. This is one reason that ...

Sure there are a few other parameters, such as velocity factor, precise delay time, and operating temperature range. In some cases, we might even have our cables fabricated by any one of the numerous ...

Wireless communications products that depend on RF principles are everywhere these days, and the growth rate is astonishing. From cell phones and wireless PDAs to Wi-Fi-enabled laptops, Bluetooth ...

An oscilloscope and a device under test (DUT) constitute a de-facto system. In it, the most overlooked element is the interface between the two: the oscilloscope’s probes. Test personnel simply grab ...

A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...

High-speed circuit design is one of the most fundamental, yet challenging areas of electronics design. High-speed circuits are commonly used today, as standards like USB, HDMI, and PCIe require most ...

Over the past decade, demand for nano-electrical characterization has rapidly increased due to the continuous miniaturization of electronic devices. The semiconductor and microelectronics industries ...
