Silly Job Title: Master Planner
This video is part of the New Book Teardown feature of my video blog.
In this video I take a look at Learning the Art of Electronics: A Hands-On Lab Course by Thomas C. Hayes and Paul Horowitz published in 2016. The book has 1,140 pages and is a companion to The Art of Electronics 3rd Edition.
Some notes about things of interest we noticed in the book:
- Xilinx was an American technology and semiconductor company, now owned by AMD
- the Ebers–Moll model is useful for modelling Bipolar junction transistors
- Hysteresis is the dependence of the state of a system on its history
- Wien’s bridge is used for precision measurement of capacitance in terms of resistance and frequency
- Wilson current mirror is a three-terminal circuit that accepts an input current at the input terminal and provides a “mirrored” current source or sink output at the output terminal
- a Bessel filter is a type of analog linear filter named in reference to Friedrich Bessel who developed the mathematical theory
- the video about the 6502 I watched recently is: The 6502 CPU Powered a Whole Generation!
- the Cypress PSoC is a family of microcontroller integrated circuits by Cypress Semiconductor

This video is part of the New Book feature of my video blog.
In this video I review the venerable The Art of Electronics 3rd Edition by Paul Horowitz by Winfield Hill published in 2015. This monstrous tome includes some 1,220 pages.
This is a long video, because this is a long book!
While I was writing up these notes for the video I found a wealth of fun stuff. Here are a few links:

Final round of Silicon Chip books
My good friend Dubz shouted me another round of Silicon Chip books as can be seen here. I now own all the books which have been marked and I’ve pretty much purchased everything that was left.

A truly incredible fact about the number 37
This is cool: A truly incredible fact about the number 37. I didn’t read it closely but 37 is my lucky number, so it held some interest. The conclusion is:
37, the median value for the second prime factor of an integer; thus the probability that the second prime factor of an integer chosen at random is smaller than 37 is approximately one half.
