2 Bit Full Adder Logic Circuit. Ni multisim live lets you create share collaborate and discover circuits and electronics online with spice simulation included. First connect vcc 5v and gnd supply to logic ic input a b is connected to the xor gate input then and gate input output of first xor gate pin 3 is connected to the next xor gate input pin 4 and cin connected to xor gate input pin 5.
Second and gate takes a b cin as inputs. It is used for the purpose of adding two single bit numbers with a carry. Output carry and sum typically represented by the signals cout and s where the sum equals 2cout s.
It is used for the purpose of adding two single bit numbers with a carry.
The half adder determines the least significant bit of the sum as the xor of the least significant bits of the inputs. A 3 11 and b 1 01. The least significant bit does not require a full adder as there is no carry input. Multi bit adder using full adder.
