Half Adder Stick Diagram. Butthe result for 1 1 is 10. Mirror adder stick diagram abc i v dd gnd b c o ac i c o c i ab s ee141 14 ee141 s04 the mirror adder the nmos and pmos chains are completely symmetrical.
We can also express it as a circuit diagram which takes up more space but also makes it easier to see how data flows. Full adder using half adder. Similarly for the carry output of the half adder we need to add y a b in an or configuration.
Full adder using half adder.
Mirror adder stick diagram abc i v dd gnd b c o ac i c o c i ab s ee141 14 ee141 s04 the mirror adder the nmos and pmos chains are completely symmetrical. Similarly for the carry output of the half adder we need to add y a b in an or configuration. If any of the half adder logic produces a carry there will be an output carry. So we add the y input and the output of the half adder to an exor gate.
