Experts of the field
It is great to have someone with immense expertise in the field to be sharing secrets regarding the industry. It takes an expert to know what are the dos and don'ts that we all need to practice and avoid. Without trade secrets from professionals in the field, we can never learn to know what to expect in the future ahead.

Re: Welcome back Kendall
Thanks Steve - great to be back on the planet's #1 Analog forum!  Looking forward to re-releasing almost 40 Filter Wizard pieces on one handy forum.  Whether you read them ten years back or are new to the material, I hope you all enjoy it.  And with luck we'll find a way of getting your questions and comments back to me.

Well, it turns out that we can perform impedance scaling on actual components; let’s look at how we deploy key properties of the humble op-amp to do this.
Designing a filter using a spreadsheet. No sophisticated charts, no pole zero relationships, determination of a response type, none of those overly complex equations I learned in school.
We set out to eliminate the inductors in our LC lowpass filter – and ended up doubling the number of them! We’ll see shortly just how these can be made to disappear in one mathematical stroke
Using optimization to design circuits (some might call it organized guesswork – for some algorithms, that’s a pretty good description) isn’t a new insight.
Why did I want to set my source and load resistances to the same value?
