Today National Semiconductor Corp. unveiled two high-speed, low-distortion differential amplifiers and two high-speed, low-power, 12-bit analog-to-digital converters (A/D converters) that provide the most accurate signal capture at the lowest power consumption.
Are we making light of Electronic Ballasts?

Way to go, Sanjaya! Rave reviews of Sanjaya Maniktala's book on switching power supply design identify it as the new "bible," the absolute definitive text on this subject. Planet Analog is proud to have "discovered" him, to have published excerpts, and invites you read his current column. This one is on the reliability of electronic lighting ballasts in India, where the wiring is frayed, the temperature sizzles, and ownership of fluorescent tubes constitutes bragging rights. Afterwards, we'll se
An introduction to analog circuit design* Part 1: Transistors and Elementary Circuits

Modern circuit design is a "mixed signal" endeavor thanks to the availability of sophisticated process technologies that make available bipolar and CMOS (Complementary Metal Oxide Semiconductor), power and signal, passive and active components on the same die. It is then up to the circuit designer's creativity and inclination to assemble these components into the analog and/or logic building blocks necessary to develop the intended system on a chip. In this 6-part tutorial, based on a forthcomin
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.
