Nanowire crossbar is an efficient nanoscale architecture which can be used for logic circuit design. In this work, we study and compare different crossbar nanoarchitectures and their application in logic circuit implementation. To evaluate the performance of crossbar architecture compared to the conventional CMOS logic design, we have implemented logic circuits using both approaches. The equiva...

Superconducting Single-Flux-Quantum (SFQ) devices have been paid much attention as alternative devices for digital circuits, because of their high switching speed and low power consumption. For large-scale circuit design, the role of computer-aided design environment is significant. As the characteristics of the SFQ devices are different from conventional devices, a new design environment is re...

If a logic circuit was specialized to a specific input, the derived circuit would be faster and smaller than the original. This study presents various designs of a key-specific AES encryption circuit. In our iterative design, 41% of the logic gates and 20% of RAM were reduced, while 24% more performance was derived. In our pipelined design, 54% of the logic gates and 20% of RAM were reduced, wh...

Short-circuit evaluation denotes the semantics of propositional connectives in which second argument is evaluated only if first insufficient to determine value expression. Compound statements are from left right. widely used programming, with negation and sequential conjunction disjunction as primitives. We study question laws axiomatise short-circuit evaluation. In MSCL (memorising logic), ato...

A new low-power design method based on multiple low swing internal voltage values is proposed in this paper. It can be applied in logic circuits, which are designed with different logic family techniques such as Complementary Pass Transistor Logic (CPL), Domino Logic and Cascade Voltage Switch Logic (CVSL). The goal of this method is the reduction of the circuit power dissipation, with only a n...

In this paper we investigate single electron tunneling (SET) devices from the logic design perspective, using the SET tunnel junction’s ability to control the transport of individual electrons. More in particular, we investigate the behavior of a modified version of the SET turnstile circuit and propose applying the circuit as a single electron encoded logic (SEEL) memory element. We analyze th...

1.1. Digital IC Technologies and Logic-Circuit Families The chart in Figure 1 shows the major IC technologies and logic-circuit families that are currently in use. Members of each family are made with the same technology, have a similar circuit structure, and exhibit the same basic features. Each logiccircuit family offers a unique set of advantages and disadvantages. In the conventional style ...
