LED drivers keep pace with light Product News 1/30/2003 Post a comment ON Semiconductor says its NCP5008 and NCP5009 white-LED drivers are among the first to accommodate external phototransistor feedback to provide automatic adjustment of LED brightness according to ambient light.
Passives makers actively eliminate lead Product News 1/30/2003 Post a comment Driven by the European Union's move to ban lead in electronic assemblies by 2006 as well as a similar move in Japan, many passive-component manufacturers are well ahead of the deadline to phase out lead in electronic components.
ADSL2 Helps Slash Power in Broadband Designs News & Analysis 1/30/2003 Post a comment As ADSL deployments continue to grow, power consumption will remain a key concern in DSL equipment designs. The ITU's new ADSL2 specs address this issue head-on, delivering two new power management modes.
Mixed-Signal PLD builds multi-voltage power supply News & Analysis 1/30/2003 Post a comment Proponents of programmable analog have long argued that their utility extends way beyond prototype development for analog circuits. In this promotional article, a Lattice Semiconductor engineer shows how a programmable mixed-signal device - one combining both programmable logic and programmable analog functions - can serve as a multifunction power supply controller, integrating many sequencing, monitoring and supervisory functions with a single device.
Searching for the right keys News & Analysis 1/29/2003 Post a comment The advertisers were right. That car you're driving is not your father's automobile. It's a large and increasingly complex network of electronic subsystems and components.The transformation reflects a quiet but ongoing revolution in automotive design. Features that not long ago were considered ground-breaking, like automatic braking systems, electronic ignition systems, airbag restraints, and rear-seat video entertainment, are now accepted as standard. An old friend, John Mayer, has this report.
Improving DQPSK Receiver Design for Satcom Apps News & Analysis 1/23/2003 Post a comment Traditional design methodologies fall short in allowing designers to achieve the performance required in DQPSK receivers. To combat the problem designers must turn to a new design flow that combines a tops-down design with bottoms-up verification.
Baseline JPEG compression juggles image quality and size News & Analysis 1/23/2003 Post a comment In this JPEG picture-processing tutorial - another of the many outstanding DSP-related stories on consumer algorithm processing slated for EE Times' January 6th Signals section -- Analog Devices engineers offer insight into the scanning and encoding techniques used to affect JPEG compression. Unlike other versions of the article, this one does the math.
CMOS op amp gives pulse generator low parts count News & Analysis 1/22/2003 1 comment The natural choice for generating a pulse of variable frequency and duty cycle is a good bench-top pulse generator. If you don't have a generator or must build one into your system, however, you can do it with a few op amps and some external components. Maxim's Roger Griswold shows how.
LVDS, CML, ECL-differential interfaces with odd voltages News & Analysis 1/21/2003 Post a comment While some interface technologies such as ECL and CML focus on ultra speed, others concentrate on multiple attributes. LVDS for example, offers both high-speed and low-power operation. National's interface expert, John Goldie, tells what you should know about some of today's popular high-speed differential interface technologies.
Components distributors hope it's Bluetooth's year Product News 1/21/2003 Post a comment If there is an industry that needs the Next Big Thing to drive growth, electronic components is it. And in 2003, Bluetooth technology-enabled in cell phones, headsets, PDAs and even PCs and peripherals-could be the long-awaited driver. That possibility has not been lost on components distributors. Avnet, an earlier believer in Bluetooth, opened its first Bluetooth design center-under the auspices of Avnet Radio Frequency Design Services-in Singapore in May 2001. Avnet quickly began offering a Bl
Understanding the 3G-324M Spec: Part 1 News & Analysis 1/21/2003 Post a comment Although an all IP wireless network is years away, designers must build systems today that support video and other multimedia. Through the 3G-324M spec, designers tap into the existing circuit-switched network to deliver these services.
