Adding Spice Models to LTspice

Tags: 

Finally... a new tutorial. Who could have ever guessed that life in the real world would be so busy (note the sarcasm!)? This tutorial is going to cover adding custom Spice models into your LTspice simulations and library. While it is very easy once you know how to do it, there are a couple pitfalls that nearly caused me to go crazy and rip my hair out in the past. Hopefully this will save you some time and stress, and possibly a hole in your monitor. Now let's get started!

  1. Finding and Downloading the Spice Model
  2. Adding the Spice Model to your LTspice Library
  3. Using the Spice Model in a Circuit
  4. Conclusion and tl;dr (too long;didn't read)

Geometric Series Derivations and Equations

Tags: 

The Geometric Series is often encountered in electrical engineering and signals and systems type problems. Therefore, I think that it is a good idea to understand where the equations to solve it come from, and how to derive them. When I search the net, it is hard to find a single place that shows all the forms and equations in one place (sometimes we just want the answers) and also shows how to derive them and an easy way to remember them.
