A Five Input Majority Gate in Quantum-Dot Cellular Automatta

Akeela R., Wagh M.D., Lehigh University, US

We present a five input majority gate (MAJ5) designed in the quantum-dot cellular automata (QCA) technology. Unlike previous designs, our design is planer, uses integral cell placement and allows inputs and outputs from the peripheral [...]

A Fan-in Bounded Low Delay Adder for Nanotechnology

Sun Y., Wagh M.D., Lehigh University, US

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 [...]

Implementation of Comparison Function Using Quantum-Dot Cellular Automata

Wagh M.D., Sun Y., Annampedu V., Lehigh University, US

Quantum-Dot cellular automata (QCA) architectures represent the future of computing. But it can only implement an inverter and a three input majority gate directly. Consequently very few QCA architectures are available in literature. By fixing [...]

Approximate Pattern Matching in Nanotechnology

Annampedu V., Wagh M.D., Agere Systems Inc., US

Approximate pattern matching is comparing an unknown pattern with a database of stored patterns with a specified error tolerance. This ability to compensate for real world sensor errors makes approximate pattern matching an ideal choice [...]
