In this paper, we present a simulation study on clocking misalignment tolerance of pipelined magnetic quantum-dot cellular automata (MQCA) architectures. By the three-phase pipelined clocking and deduced clocking misalignment model, a systematic evaluation of impacts of clocking misalignment on four fundamental MQCA architectures is performed at non-zero temperatures. It is found that for the fixed...
Quantum-dot Cellular Automata (QCA) is an emerging nanotechnology, with extremely small feature size and ultralow power consumption comparing with transistor-based technology. Anteriority, basic level-triggered flip-flop designs based on QCA implementation were examined. In this paper, we utilize the unique QCA characteristics and clock zones to design falling edge-triggered J-K flip-flop that is...
