1bit full adder requires 9 NAND gates, which leads to a total of 36 transistors, which is better comparing with the one that uses XOR, AND and OR gates. So to make a 4bit full adder we would have 4 x ...

I’m really glad to share that, this is my seventh project on Cadence Virtuoso. I am designing here a 8T 1-Bit Full Adder Design and Analysis With Layout Using Cadence Virtuoso. An 8T 1-bit full adder ...
