SINGLE-BIT ADDER Russian patent published in 2010 - IPC G06F7/50 

FIELD: physics.

SUBSTANCE: device has 14 p-type conductivity field-effect transistors, 14 n-type conductivity field-effect transistors, inputs for terms A and B, a carry input C_IN, high and low level voltage power leads, a first inverter whose output is the carry signal output C_OUT of a second inverter, whose output is the output of the summation result S.

EFFECT: faster generation of the carry signal owing to less capacitive loads in the circuit for transmitting the signal from the carry input C_IN to the output of the summation result S.
