Ripple carry adder
Refer : https://gateoverflow.in/8250/gate2015-2-48 Here i dont understood how they calculated 12ns . I got that the first full adder will take 4.8ns time at that 4.8 ns we'll get the carry as well as the sum, in that duration the first XOR Ai ... for subsequent operands but for final sum the carry first need to be propagated through all full adder first Why 4.8 + 3*2.4 ??

Full Adder
The Cout function of a 3-bit adder is as follows: AB + Cin (A ⊕ B) ----- i It, being a majority function, can also be written as: AB+BCin+CinA which is equivalent to AB + Cin (A+B) ------- ii So, if we consider eqn i and ii, doesn't it show that (A ⊕ B) = (A+B). What am I missing here?
