Present a better image: TFT panels spearhead displays upgrade

- BY GRAHAM PROPHET • EDITOR
ONE OF THE EFFECTS OF THE RAPIDLY MULTIPLYING NUMBER OF POWERFUL CONSUMER PRODUCTS IN THE MARKETPLACE IS THAT IT RAISES EXPECTATIONS. USERS DEMAND A WELL-DESIGNED ELECTRONIC PRODUCT—EVEN IF IT THEY DO NOT EXPECT IT TO REPRODUCE MULTI-MEDIA CONTENT—TO HAVE AN ATTRACTIVE AND SOPHISTICATED DISPLAY. ANOTHER, AND FORTUNATE, EFFECT IS THAT THE COST OF ADDING SOPHISTICATION IN THAT DEPARTMENT IS FALLING.

REACH OUT AND TOUCH

4G wireless: EVOLUTION OR WATERSHED IN SOC ARCHITECTURES?

- BY RON WILSON • EXECUTIVE EDITOR
THE NEXT STEP IN WIRELESS TECHNOLOGY COULD PROVE THE TIPPING POINT FOR MULTICORE EMBEDDED PROCESSING.

Reducing output-voltage noise in power supplies

- BY KEVIN FRICK • MAXIM INTEGRATED PRODUCTS
MANY LDOs ON THE MARKET TODAY SUCCESSFULLY GENERATE VERY LOW OUTPUT-VOLTAGENOISE LEVELS. HOWEVER, EVEN THOSE LEVELS MAY NOT BE LOW ENOUGH FOR CERTAIN CLASSES OF APPLICATION, WHICH CAN BENEFIT FROM MORE NOISE REDUCTION THAN THE LDO ALONE PROVIDES. THIS ARTICLE DISCUSSES AND COMPARES THREE CIRCUITS THAT LOWER THE OUTPUT-VOLTAGE NOISE: TWO EMPLOY NOISE-FILTERING TECHNIQUES, AND ONE A FEED-FORWARD TECHNIQUE.

Distributed linear regulators increase output current and spread the heat

- BY ROBERT DOBKIN • LINEAR TECHNOLOGY
PARALLEL-BOARD LAYOUT AND HEAT SPREADING OFFER DESIGNERS NEW WAYS OF USING LINEAR REGULATORS IN ALL-SURFACE-MOUNT APPROACHES. THESE TECHNIQUES WORK WELL IN TODAY’S HIGH-PERFORMANCE, HIGH-DENSITY PCBs.
