The Squeaky Wheel Gets the Repair
Brad Albing 6/27/2013 15 comments
Using MEMS devices, sophisticated algorithms, and integrated functionality, vibration and temperature sensing can spot problems in bearings and other rotating apparatus and head them off before they become catastrophic.
Keeping the Family Business Going

There is a certain sound you can only get from some of the old ribbon microphones. But you need a preamp with comparable quality and compatible with the other technical criteria.
More Thoughts on Interleaved ADCs
Jonathan Harris 6/26/2013 6 comments
We continue our discussion regarding achieving higher sample rates in an analog-to-digital conversion system. Multiple ADCs reduce the sampling requirements for each device, but timing is critical.
Digital & Analog Blend in Today's PHY
Brian Bailey 6/25/2013 19 comments
The blending of digital and analog in mixed-signal devices leads to some innovative interfaces between subsections and to the external world. Since power should be conserved, these interfaces use new, improved techniques.
Is Communications a Lost Art?
Brad Albing 6/24/2013 45 comments
Business communications should be easy and straightforward. The easier it is, the more likely the companies involved will thrive and prosper. Does it always work that way?
Do Analog ICs Still Need Perfection?
Analog Angle 6/20/2013 7 comments
The combination of analog functions and digital processing and memory on a single IC means that many historical source of signal-chain error can be erased, but some still remain.
The Future of Medicine Is Here

A more clever method of electrically stimulated transdermal drug delivery was recently described in a paper presented at the IEEE International Solid-State Circuits Conference.
Designing With Op-Amps Is Ending
Scott Elder 6/11/2013 47 comments
Are we being forced to move away from discrete IC designs and towards integrated analog designs? The answer may lie within the models that IC manufacturers provide for us to use in our circuit simulations.
Duct Tape, Spit & Baling Wire
Ransom Stephens 6/6/2013 15 comments
What do you do when ground currents flow where they're not supposed to but don't flow where they are supposed to? Baling wire may solve the problem. Duct tape is optional.
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.
