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.
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.
MPEG-4 toolkit improves on motion vector calculation News & Analysis 1/8/2003 Post a comment Digital video, with its inherent quality, reliability and flexibility advantages over traditional analog video, is showing up in a wide range of applications. Unlike analog video, signals in the digital domain allow users to view, access and manipulate content in entirely new ways. In this MPEG-4 tutorials - one of the many outstanding DSP-related stories on consumer algorithm processing slated of EE Times' January 6th Signals section - TI engineers offer insight into the features that elevate M
On-Chip RF-Isolation Techniques Design How-To 1/8/2003 Post a comment Higher frequencies, higher integration levels, and increased analog content on mixed-signal chips is making on-chip isolation more difficult for designers. In this feature article, authors from Cadence and Atheros describe several commonly used isolation techniques that you can often combine to protect your chip designs from noise-induced problems.
Battle-hardened veterans of the electronics industry have heard of the “connected car” so often that they assume it’s a done deal. But do we really know what it takes to get a car connected and what its future entails? Join EE Times editor Junko Yoshida as she moderates a panel of movers and shakers in the connected car business. Executives from Cisco, Siemens and NXP will share ideas, plans and hopes for connected cars and their future. After the first 30 minutes of the radio show, our listeners will have the opportunity to ask questions via live online chat.
