We consider a realization of the XOR logic gate in a process biocatalyzed by an enzyme which can be inhibited by a substrate when the latter is inputted at large enough concentrations. A model is developed for describing such systems in an approach suitable for evaluation of the analog noise amplification properties of the gate. The obtained data are fitted for gate quality evaluation within th...

In this article, we analyze the circulant structure of generalized circulant matrices to reduce the search space for finding lightweight MDS matrices. We first show that the implementation of circulant matrices can be serialized and can achieve similar area requirement and clock cycle performance as a serial-based implementation. By proving many new properties and equivalence classes for circul...

In February 2013, Altera and Intel Corporation jointly announced that the next generation of Altera’s highest performance FPGA products would be produced using Intel’s 14 nm 3-D Tri-Gate transistor technology exclusively. This makes Altera the exclusive major FPGA provider of the most advanced, highest performance semiconductor technology available. To understand the impact of Tri-Gate technolo...

Exclusive-NOR (XNOR) gates are important in digital circuits. This paper proposes the novel design of 2T XNOR gate using pass transistor logic. The proposed circuit utilizes the least number of transistors and no complementary input signal is used. The design has been compared with earlier designed XNOR gates and a significant improvement in silicon area and power-delay product has been obtaine...

Application of quantum-dot is a promising technology for implementing digital systems at nano-scale.  Quantum-dot Cellular Automata (QCA) is a system with low power consumption and a potentially high density and regularity. Also, QCA supports the new devices with nanotechnology architecture. This technique works </...

In our project, we propose a novel architecture which generates the test patterns with reduced switching activities. LP-TPG (Test pattern Generator) structure consists of modified low power linear feedback shift register (LP-LFSR), m-bit counter; gray counter, NOR-gate structure and XOR-array. The m-bit counter is initialized with Zeros and which generates 2m test patterns in sequence. The m-bi...

The paper proposes a novel design of two transistor (2T) XOR gate and its application to design an 8 bit x 8 bit multiplier. The design explores the essence of suitably biasing the MOS transistor and engineering the threshold voltage of the MOS transistor through appropriate biasing and device geometry. Using the 2T XOR gates, a full adder has been realised. Detailed simulations have been carri...

In the context of the modeling and simulation of neural nets, we formulate definitions for the behavioral realization of memoryless functions. The definitions of realization are substantively different for deterministic and stochastic systems constructed of neuron-inspired components. In contrast to earlier generations of neural net models, third generation spiking neural nets exhibit important...

Most of Exclusive-OR(XOR) logic gates on quantum-dot cellular automata(QCA) is based on configuration of 2-input, and they are hardly to be scalable and exists unbearable noise because they are only focused on decrease of latency and space. In this paper, we propose how to make a scalable logic using a wire crossing technique, and give examples of two expanded XOR gate using typical logic gates...

The two-gate bistable flip-flop may be generalised to a coupled structure of many gates having more stable states. These multi-flop structures have applications as arbiters to control mutually-exclusive access by several concurrent processes to a single service or resource. The paper illustrates some aspects of their complex dynamic behaviour.
