I was filling out a group of standard internet security questions and the one that is almost always front and center stood out to me.

What is the name of your favorite teacher?

Of all the milestones we remember in our lives our favorite teacher is almost always a part of it.

Teachers shape futures.

When I was studying engineering my teacher was a hard, no-nonsense, by-the-book, German engineer named Rudy Ströebel. Herr Ströebel demanded I memorize the resistor color codes, formulas I would need, and schematic symbols and their meanings before he would begin teaching me. This was not a good way to absorb learning but, none the less, I wanted desperately to know and understand all he knew. The deal was made and off to studying, I went.

He wasn’t my favorite teacher though I owe Herr Ströebel much. Without his patience and guidance, I would not be who I am today.

Teachers shape lives.

My favorite was my 4th-grade teacher. I was her pet student and every afternoon at the close of school she would let me carry books and stacks of paper to her car—a brand new pink Cadillac with an electrically operated trunk—as futuristic to me as a flying saucer. With a nervous finger, I would press the trunk button under the massive steering wheel and up popped the trunk. It was pure science fiction. I loved that electric trunk and the teacher who let me operate it.

Whether teachers are from our past or in our future, they are wonderfully gifted, generous people the world needs more of.

To our teachers.

Another piece to the puzzle

One of my favorite stories comes from a kindergarten student brought before the teacher to face charges of selfishness.
“It seems you do not like to share with the others.”
“Oh, I do! I just don’t like them messing with my stuff.”

The vast majority of integrateds achieve their compactness from a shared power supply, but this design technique shortchanges performance. As I mentioned in yesterday’s post, all the major benefits we might expect when building an integrated, such as, eliminating interconnects, and matching colorations of components within the system can be diminished or lost when power supplies are shared.

The importance of power cannot be overstated. After all, an amplification device is nothing more than a modulated power supply. And yet designers in our field have consistently treated the source of power as an afterthought, like the proverbial red-haired stepchild (apologies to any of you qualifying on both accounts). The single biggest problem in the artform known as the integrated is the shared power supply and, even if you went to the trouble of assigning each system its own, you still feed them with one shared power cord, thus losing benefits enjoyed by separates.

Sharing has its joys, but power supplies and cords need to be selfish.
