Proper Layout and Component Selection Controls EMI News & Analysis 9/30/2003 Post a comment Understanding the physics of voltage-regulator topologies is important when designing power systems for EMI and EMC compliance. In particular, the physical principles behind switching regulators (buck, boost, flyback, and SEPIC topologies) guide component choice, magnetics design, and PC board layout. Parasitic elements such as leakage inductance, ESR, and ESL are significant when optimizing circuit performance.
Garmin GPSMap 76S: Sensory overload Teardown 9/29/2003 Post a comment Besides a GPS longitude-latitude position indicator, the GPSMAP from Garmin is an altimeter electronic compass. It has specialized magnetic sensors, and a variety of ICs from suppliers like Cirrus Logic, Fairchild, Linear Technology, and Maxim. David Carey opens the case to show what's inside.

Dropping anchor News & Analysis 9/29/2003 Post a comment While highly competitive pricing for electromechanical switches and relays is good news for OEMs, U.S. suppliers of the devices are struggling to achieve profits while vying for shrinking orders.
STMicroelectronics sets sights on China News & Analysis 9/29/2003 Post a comment Refusing to be outdone by competing integrated device manufacturers or made outmoded by pure-play foundries, STMicroelectronics N.V. last week sketched an ambitious manufacturing strategy designed to keep the company at the near-bleeding edge of chip- makers.
AMD throws 64-bit challenge at Intel News & Analysis 9/29/2003 Post a comment In a bold attempt to leapfrog Intel Corp., Advanced Micro Devices Inc. last week introduced a family of 64-bit processors for mainstream PCs that it hopes will mark the beginning of the end for 32-bit computing.
Wafer prices on the move, FSA reports News & Analysis 9/29/2003 Post a comment Fabless semiconductor companies and integrated device manufacturers (IDMs) are facing sticker shock as foundries, emboldened by rising plant utilization and improving demand, have begun hiking wafer prices in a bid to recoup their investments.
CD-quality car radios closer to realization News & Analysis 9/29/2003 Post a comment The move toward CD-quality car radios gained momentum last week, as Kenwood Corp. delivered the first HD Radio tuner and Philips Semiconductors said it will roll out a new chip that could help cut the cost of entry into the fledgling market.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
