This page contains several simple circuits for simulation on the Micro-cap circuit simulator. the categories covered include, some really simple circuits, simple filters, the common emmitter amplifier, and op amps and comparators.
This section contains several simple circuits for simulation with Micro-cap.
Firstly download and install Microcap by putting "Micro-cap simulator" into a search engine
there are then 2 ways of downloading these circuits to use them.
option 1, download the circuits as the zip files, There is a ZIP file link at the end of each group of circuit links.,
option 2, right click on the individual circuits and use "save as" and then open the saved file with Micro-cap.
I am suggesting the above methods as if you just left click on the individual circuits then most browsers just open the individual circuits as text,
