  • Well… it’s moving time again! With my new focus on high performance analog and signal integrity, I am moving to the famous TI blog – Analog Wire. All the original Energy Zarr Blog content will be available via our archive on the E2E...
  • In my prior two post ( Part I and Part II ) on designing industrial strength systems I discussed thermal management issues and various methods for hardening designs against EMI and ESD. In the last installment I discussed system failures due to lightning...
  • In part 1 of this blog series I talked about harsh environments which include mines, mills, chemical plants, et. al. Designing for those environments means taking into consideration extremes which normal products (e.g. consumer goods) would never experience...
  • When you think of engineering for industrial applications , my first thought goes to environmental conditions of applications such as steel mills. There are motor controllers working right next to (or attached to) giant electric furnaces and smelters...
  • If you are as old as I am, you may remember the quintessential “Op-Amp Cook Book” by Walter Jung (I have an autographed copy) or the must have “Intuitive IC Op-Amps” by Tom Frederiksen (I also have an autographed copy). Many of...
  • Whether 'tis nobler to signal via complementary means, or to take arms against a sea of noise… ah, but I take literary license with Shakespeare. But it does raise a real question… should a designer use differential or single ended methods...
  • Now I’m sure as engineers we have all studied circuit modeling. SPICE is an amazing tool to emulate how your final circuit might perform… but what’s really interesting is that passive components such as resistors, capacitors, inductors...
  • In my previous blog “ Where Did I Go Wrong? Funny Mistakes in Electrical Engineering ” I discussed some simple, yet devastating things that led to circuit failures. In this post, I’m going to touch on a couple items that caused several...
  • In my never ending quest to lower our carbon footprint, I bring you good tidings of progress made and lessons learned. Recently my wife and I became “empty nesters” and our two daughters are learning that a one degree change in the thermostat...
  • Tis the season to be thankful… November 22 nd marks Thanks Giving Day in the US where people gather around a table to consume a feast and give thanks for friends and family. The engineering community has much to be thankful for as well. The number...
