This paper presents an adder designed specifically for nanoelectronics. It exploits the basic characteristics of nanoelectronic technologies such as the RTD, SET and QCA to provide an adder that has a very low delay and a bounded fan-in. It is known that a low fan-in bound implies high reliability. This adder, for the first time allows user a trade-off between the fan-in bound, the complexity and the speed. A comparison with other adders available in the literature has been provided. Design of an 8-bit adder built with resonant tunneling diodes (RTD) based on these principles is presented.
