November 16, 2009 2D Communications Sheet Challenges 3D Trends
Last month, Teijin Fibers unveiled a 2D communication sheet that it says provides simple, secure wireless local-area network (WLAN) connections. According to the company, communications are rapidly migrating from 1D cable to 3D wireless topologies, while it forges development in the 2D domain. With the growing trend toward 3D communications, this 2D approach may seem like a step backward. But Teijin Fibers, which primarily designs and creates unique...

November 16, 2009 Select Optimal Protection For Your VDSL-Based Telecom Circuits
A variety of over-current and overvoltage products are on the market for protecting VDSL telecommunications circuits. These include transformer line-side capacitors, transformer driver-side diodes, thyristors, gas discharge tubes (GDTs), electronic current limiters (ECLs), and combinations of all of these devices. To actively protect telecommunication systems, engineers need to understand the surges, the damage thresholds of VDSL drivers, and the...

October 22, 2009 Select The Right Ultracapacitor Solution
Like all capacitors, ultracapacitors have a high power density. Yet unlike their traditional counterparts, electrolytic capacitors, ultracapacitors offer high energy density, allowing them to store a vast amount of energy in a small package. The capacitors that most design engineers are familiar with have very short time constants, which means their voltage cycles quickly. Ultracapacitor arrays, though, have time constants on the order of tens of seconds to...

September 24, 2009 The Five Building Blocks Of An Efficient, High-Brightness LED Driver
As high-brightness LEDs (HBLEDs) penetrate all avenues of the lighting market, various semiconductor manufacturers are offering constant-current drivers. Only by choosing a driver IC capable of meeting the flexibility and control required by today’s applications can the true potential of HBLEDs be unleashed. Theatrical lighting, for example, often requires high dimming resolution while dynamically adjusting the current to account for fluctuating power...

August 27, 2009 Use Capacitive And Proximity Sensing In Your Digital Photo Frames
Digital photo frames (DPFs) are starting to appear in many places where traditional photo albums and frames have been used for decades. The growth and proliferation of digital cameras has rendered hard-copy photos from analog cameras all but obsolete. On top of displaying the photos, DPFs can transfer them to printers and other devices, play videos, and offer remote control over all these functions without a computer. The basic DPF uses a multimedia...

July 23, 2009 High-Density IC Packaging Looks At The Third Dimension
Much has been written in the past few months about the upcoming sunset of Moore’s Law. Stated succinctly, Gordon Moore predicted in 1965 that the number of transistors in ICs would double every 12 months1. There have been other versions of his prediction, including shifts to a performance metric and altered timeframes. However, the message is clear: a key metric doubles on a regular schedule and has for many years. Moore has also stated that no...

June 25, 2009 Converters Provide Crucial Help In EMI/RFI Shielding
Manufacturers of electronic devices employ electromagnetic interference (EMI) and radio-frequency interference (RFI) shielding to protect sensitive digital circuits from external emissions that can impair product performance, as well as to contain the potentially harmful emissions that come from their products (see “The Dark Force Of Evil In Electronics: Electromagnetic...

May 21, 2009 Proton Polymer: The Key To Double-Layer Supercaps For High-Voltage Applications
The turn of the century saw the debut of a double-layer supercapacitor technology, the proton polymer. Since its introduction, there has been much success in pulse supercapacitor applications due to the intrinsically high conductivity associated with the proton-conducting polymer separators and nanoparticle carbon powders used in these capacitors. These components exhibit a capacitance range from 5 mF to 1 F, equivalent series resistance ...

March 26, 2009 Technology Shrinks PCB Motors While Boosting Accuracy
The march for miniaturization never stops as evidenced by portable products the size of a credit card that outperform some laptop and even desktop computers. Probably one of the most challenging markets in this quest for tinier gadgets is motors and motion control. Though still daunting, shrinking a semiconductor should be less of a burden because there are no moving parts to consider. But squeezing a motor and related control circuitry onto the head of a pin is...

Save Costs With Peak-Rated Power Supplies
Traditionally, the selection of power supplies is based upon the expected maximum total system power, calculated as volts × amps = watts. But for some applications, a power supply with a peak current or peak power rating may provide a significant cost savings. For example, if the power supply’s load includes electric motors, disk drives, pumps, fans, actuators, or other components that require an initial startup current that’s much higher than the steady...

February 26, 2009 Mature Display Technology Still Viable In Advancing Markets
When we think of displays these days, the first technologies that come to mind are LCDs, LEDs and organic LEDs (OLEDs), and touchscreens. These components, though not new, proliferate and evolve because of a number of factors. Constant research and development in the electrical, mechanical, and chemical/materials disciplines uncovers ways to make these displays cheaper, more functional and energy efficient, and easier to integrate into new...

February 26, 2009 Future-Proof Low-Profile 1U And 2U Systems With High-Speed Connectors
Choosing connectors that meet increased speed and density requirements for low-profile 1U and 2U rack-mountable systems is a complex task. Increases in signal-pin counts and power consumption have turned system packaging design for optimal airflow into an increasingly difficult challenge. Common to network interfaces, storage, and telecom equipment, these lowprofile systems require long-lasting connector configurations that can...
