After we designed circuits and passed logic tests, we started studying on transistors. The first circuits we had designed were TTL, and for now, we migrated to CMOS technology. For these designs, we’ve used Alpha and Omega 6407 PMOS transistors and Texas Instruments CSD17506Q5A NMOS transistors. At this step, we designed simple logic gates, and designs are available on Github.

Example

This is NOT gate designed in StrongPC :

And if we apply some voltage at the input :
