A channel connected component (CCC).
For some reasons, I feel my friends in CAD company or my leads are not able to introduce me very well to you.
So here I am, like an open book, fully simplified. Glad to meet you
Myself, Channel Connected Component or CCC as I am being called by noise analysis engine architects. And to identify me in a circuit, you just need to know, I have 3 rules as shown in below image: 
My first rule – I receive my inputs only at my gate terminal of transistor that’s inside me
My second rule – I send outputs only to gate terminal of transistors lying outside my territory. I can also send outputs to a Primary Output of a logic device
My third rule – I have top notch connections to VDD and/or GND
Now I think, that’s not enough unless I show up myself to you inside a flip flop. So meet me in below image. I am sitting inside every logical gate, like Flipflop below:
Now my friend ‘inverter’ is not called as a CCC, unless he follows the rules I just mentioned above. Sometimes, he does follows all rules and gets recognized as a CCC. So, in above image, some of my ‘inverter’ friends do follow the rules, while few of them doesn’t. The highlighted one’s are me, being categorized as CCC.
I do have some more friends like me inside above flipflop. I am shading them as blue in below image, for a reason.

For gates like inverter, I am alone, as the inverter, by design, follows all rules which I want him to follow to be categorized as CCC. So inverters are being categorized as single-stage cells, while gates like NAND or AOI, where I am present twice, they are being categorized as 2-stage cells.
People don’t talk about me much, and so I am being neglected, but not anymore, and Thanks to Kunal for bringing me on this platform before all of you…”The most important thing in communication is hearing what isn’t said” – Peter Drucker
There’s a lot being talked about me in Kunal’s course on Library characterization and modelling – Part 1. You just might want to have a look at that course and hear a lot about me…
I will meet you in class, till then … happy learning…
