LTspice circuits

In this page I decided to list some of the most basic LTspice simulations that an introductory university level electronics course may use. Physics courses students may benefit from this material as well, so here it is.

In order to download the schematics, just click on the circuit name. Some simulations may contain Python code with further useful calculations such as time constants and rise time.

Depending on what your objective is, you may need to tweak the circuits a little bit.

I hope this circuits will be useful.
