This question might seem very basic, but it will help me a lot if someone can answer it from the basics!
I have just finished my first year at college and there was a course on digital design, where we studied the fundamentals of digital systems and also implemented various circuits using ICs in the lab.
When we saw the IC in class, we just focussed on the circuit inside the IC - how everything is connected and what logic gates/ FFs are used. But while implementing circuits in lab, I saw that there were 2 power pins also, on each IC.
Why do they need power pins? Like, all that is present in the IC is a few logic gates (even FFs are logic gates at a very fundamental level) right? Logic gates do not require power when we have to use them right?
