Garbage in / garbage out: Input filters enhance A/D converter measurements
News & Analysis  
11/27/2002   Post a comment
Analog-to-Digital Converters (A/D converters) are capable of quite impressive noise and distortion performance. However, even the best signal generators and synthesizers produce signals that are not spectrally pure enough to evaluate noise and distortion performance of A/D converters. A National apps guy reminds us that even the best test set ups can benefit from an input filter.
Differential Hall-effect sensors aid rotational speed control
News & Analysis  
11/27/2002   Post a comment
The rotational speed of motors with gear teeth can be precisely monitored and controlled with new-generation Hall-effect sensors. BiCMOS technology provides devices with high-sensitivity and speed, and yet small enough to fit inside motor housings or other tight spaces. Allegro's ace applications engineer explains their principles of operation, and provides a guideline for analog signal conditioning.
From wall plug to nano circuit: power chips go hand-in-hand with SoC technology

The conversion from bus voltage to final nanoscale load often requires low voltages at hundreds of Amperes, says this prolific Fairchild product planner. The key to efficiency, he writes in the November 18th issue of Planet Analog magazine, may have a lot to do with power factor correction... Reno Rosetti also authored an online guest column (an opinion piece) on the prospects for putting power management under digital control.
Stabilizing voltage mode converters with ceramic output capacitors
News & Analysis  
11/14/2002   Post a comment
Power supply designers have a variety of choices available when selecting output filter capacitors. This selection is typically steered by the initial design goals, whether it is lowest cost, smallest size, lowest ripple voltage, or transient load response. These Texas Instruments engineers say there's a lot of mileage to be gained from ceramics, like small size and low cost. Just watch that ESR, they advise.
Stabilizing buck converters with transconductance amplifiers
News & Analysis  
11/14/2002   Post a comment
Synchronous buck converters have received great attention in low power, low voltage DC-DC converter applications due to their high efficiency. In this application note, International Rectifier engineers show how to stabilize buck converters using as transductance device as the error amplifier in the voltage regulation circuit. A transconductance amplifier, they point out, multiplies the difference of input voltage with a certain gain to generate a current into the output node. These guys offer t
PCB Design-Tool Progress Continues Slowly
Design How-To  
11/6/2002   Post a comment
Compared to chip design-tool development, advancements in the PCB design-tool arena are not very dynamic. TechOnLine's Jim Lipman discusses why he thinks PCB tool development is so slow and what PCB tool vendors need to do to address upcoming system-design problems.

Why Connect a Car?
May 11, 1pm EDT Monday
Overview: 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.
