New QCA T flip flop and 4-bit counter structures

TFlip-Flop designing,-QCA-,optimized counter,nanotechnology

Problems of shrinking CMOS transistors’ sizes in order to miniaturize the circuit & decrease the power consumption of integrated circuits specially in digital integrated circuit (VLSI) persuaded the researchers to use the newer & better ways for building the logic gates. One of the proposed methods is use of quantum cellular automata which is presented to design the logic circuits and in recent years, has paid attention to it. In this paper, we could design the optimized T Flip-Flop model from the used cell numbers point of view by QCA technology so that we achieve an optimized 4 bit counter, thereby the occupied space would be shrunk.
