Title: [Electronics] 1 Bit Full Adder - Ripple Carry (Transistor NAND Logic)
Post by: xor on May 12, 2015, 07:01:34 AM

This is a 1 bit ripple carry full adder using pure NAND gates, constructed with transistors.
I have excluded resistors and power rails for simplicity.

Looks darn sexy. What does it do. Does it have an software equivalent?
Could you clarify it to us a bit more, since we are complete noobs? :P
Thanks!

Kek, it's software equivalent is roughly 1+1 = 10 :p

Since I'm way too lazy to explain it all, this post I googled quickly seems like it should work:

I am going to create a digital logic series of tutorials.
For ease of updating, I will be hosting them on GitHub.

https://github.com/XorLogic/DigitalLogic (https://github.com/XorLogic/DigitalLogic)

Tutorial 01. Digital Logic Primer is up.
This will be the precursor to fully explaining what is happening with this 1 bit full adder.
