I Still Have a Vacuum Tube in My House?

: The legendary vacuum tube still has an irreplaceable role in mass-market and specialized applications, but that too may be changing due to progress in solid-state devices and designs.
Supergroup Van Halen Was Once Used to Promote PCs

It may come as a shock that PCs were not always common in life and music was once generated through ANALOG technology of vibrating guitar strings altered by pushing pedals, pulling levers, and twisting potentiometers.

The data sheet for the amplifier that I’ve chosen for my application specifies a small signal bandwidth along with a large signal bandwidth, and they are quite different specs. How do I determine if my signal qualifies as small or large?
Diff-Amp Uses a Resistor Network

Low-cost integrated resistor networks can be used to implement a low-parts-count two-op-amp differential amplifier with low common-mode gain. Integrated onto a common substrate and processed together, resistors of integrated networks match well and are an alternative solution to discrete resistors, especially for amplifiers with a wide common-mode input voltage range.
An exclusive look inside the Data Center

Google has recently joined the Open Compute Project (OCP), and has announced a 48V DC power distribution technology to the rack and then down-converted to 1VDC or less as close to the processor as possible.
PI Continuum Simulation: Load Modulation
Raj Nair 4/7/2016 Post a comment
How do advanced design changes impact power integrity? This is a question often encountered by power-integrity aware IP block designers. And here is where a front-end analysis environment such as Anasim's PI-FP is most useful.
The Benson High-School Electronics Class Rose Festival Prank
Dennis Feucht 4/6/2016 Post a comment
Every year, a big festival is held in Portland, Oregon - the Silicon Forest - that is not quite as famous as the Pasadena Rose Parade, though its parade was carried on network television in the 1960s, when I was in high-school. In the mid-‘60s, Benson Polytechnic High School was rated nationally as number two behind the Bronx School of Science in New York
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.
