In this paper, a novel 3-input AND gate with one clock zone and area same as one AND gate, is proposed. The idea uses two-layer majority gate. A bias is applied from the top of the majority. To implement an AND/OR gate, the bias should be "0" or "1" respectively. The bias changes the equilibrium point of the polarization.
In recent years, researchers have been interested to implement computational circuits by nanotechnology since it has many attractive advantages. Quantum-dot cellular automata (QCA) is one of the most attractive and profitable nanotechnology that was first proposed in 1993. A design of ring counter was introduced in 2008 for the first time. After that, a 4-bit counter based on ring counter, was proposed...
