Abstract :
The ability to control the transport of individual electrons within single electron tunneling based circuits creates the conditions for implementing single electron encoded threshold logic gates. This paper investigates the implementation of binary addition based on such gates. We first propose implementations of full adder and 4-bit lookahead carry generator blocks and verify the designs by means of simulation. We then evaluate the area, delay, and power consumption of 16-bit and 64-bit ripple carry and carry-lookahead adders based on these blocks.
