Analog switch focus: cell phone features spur demand for analog switches
Articles 12/13/2004 Post a comment
This has been a big year for the analog switch market, which has seen demand leap forward as the replacement of discrete components in cell phones accelerated. Such vendors as Analog Devices, Fairchild Semiconductor, Maxim Integrated Products, Siliconix and Texas Instruments have been churning out new switches in response to the feature-hungry demands of the cell phone market.
Switch Mode & Pulse Transformers for Hipot Up to 40 KVAC
Articles 12/9/2004 Post a comment
The encapsulated Switch Mode and Pulse Transformers for high frequency switching applications, from Bicron, have been specifically designed to meet the high reliability demands for BIL (Basic Impulse Level) ratings at the PCB level found in power management, power control, and power conversion systems.
Focus on D/A converters: D/As ride LVDS to gigasample realm
Articles 12/8/2004 Post a comment
As signal-processing requirements increase in speed and complexity, system designers require data converters that can synthesize high-quality signals at much higher frequencies than ever before. Fujitsu Microelectronics America Inc. and Analog Devices Inc. are meeting these needs using low-voltage differential-signaling (LVDS) inputs to boost sampling rates in digital-to-analog converters. Find out if other companies are building these products.
Where should that diode go?

Using a pulse width modulator to drive a solenoid allows a significant reduction in power dissipation but it can cause a great deal of noise. Bill Klein is back with new report for his popular trouble-shooting column, "A call I took last week."
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
