Signal and Power Integrity by Eric Bogatin was recommended to me for learning how to do high speed PCB design.  I’m heavily dyslexic so it’s going to take me a bit to get through it so I think I’ll track my progress here.

Eric Bogatin also appears to have several articles on EDN and has a host of video courses on-line that appears to be sponsored by LeCroy.

After reading several chapters I have realized that there is so much information that I beginning to forget some of the subject matter.  This is mainly due to the fact that I’m just reading the book and not reenforcing the data.  The best way to reenforce the data is to apply the knowledge to a project, create a report on the subject mater, or try to teach the subject to someone else.  I’ve got plans on applying the knowledge but I really need to get through the book first so I’ll have to start creating a summary report for each chapter.

I have been able to utilize some of what I have already learned in my work at Tolteq…. didn’t really expect that. I don’t do anything high speed at Tolteq, but I do design the bulk of the downhole (175°C) boards used by the company and I recently came across some issues dealing with impedance matching in some ADC measurements.  I was able to immediately identify the issue as an impedance matching problem, made a few adjustments to some resistors and fixed the issue quickly. I was also able to recognize some o-scope measurements issues when dealing with some digital signals and make appropriate changes to the measurement method to get rid of some false negatives.

DesignCon has caught my attention. It’s in Santa Clara at the end of January and costs about $800, if you want to attend the conferences.  I would love to go, but I’m not knowledgeable enough, YET, to get a lot of out it plus it would be very expensive for the registration + room and board + flight + PTO from work….. maybe next year.

circuit boardThis is a big deal.  It looks like Altium has created a hobbiest version called CircuitMaker.  I signed up for the beta, more to come….

Dark and Stormy Nights

I love murky 30-50 style scary/funny movies like Murder by Death, Clue, Private Eyes, and Dark and Stormy Night.

I need a manor house on a hill, with hidden passages, with the only access across a old bridge, and built in a location that has mostly raining nights.
