Yes, basically, anything with more than 2 connectors and that has silicone on it is an IC.

If you don't wish to use IC's than go old school, and look into building circuits with Tubes.

But they are hard to find, and are not manufactured much any more. if at all.

Plus they use up tons of power to run.

Not at all. Use what your comfortable with.

Think about how much circuitry you would haft to string together to create an op-amp.

That would be a double sided board all on its own.

And technically a transistor is an IC.
