Comparative analysis of 1-bit memory cell in CMOS and QCA technology

Circuit designing with quantum dot cellular automata is one of the most recent technologies which aim at scaling of devices. In this logic design technique, the organization of quantum cells defines the circuit. It is based on field coupled computing. The quantum dot cellular automata has numerous advantages including less area occupied, lack of interconnects, higher clock frequency, and since it doesn’t involve transfer of electrons or flow of current, it has the potential to perform low power calculation. This paper presents the comparison of 1-bit memory cell designed using CMOS technology and quantum dot cellular technology. The quantum dot cellular technology results in lesser occupied area at high clock frequency.
