A wonderful and magical history
When dad CMOS and mom MOS love each other very much, they make a wish and then little “NAND” is born.
So logical gates are nothing more than transistors, which have a single logical output, nowadays with the help of science, humans managed to make a single device out of transistors within an array of semiconductors.
Does that means that a logical gate have tiny little microscopic transistors?
Well in a figurative way it does, but i didn´t found any microscopic transistors when i sliced one of my logical gates yesterday, this logical gate is made with an array of semiconductors so we can have the logical gate we need.
