In this paper a circuit design technique to improve noise tolerant of a new CMOS domino logic family called feedthrough logic is presented. The feedthrough logic improves the performance of arithmetic circuit as compared to static CMOS and domino logic but its noise tolerant is very less. A 2-input NAND gate is designed by the proposed technique. The ANTE (average noise threshold energy) metric...

A logic-to-logic comparator (LLC) is a tool that verifies VLSI layouts by comparing the logic diagrams for a circuit with structures extracted from the circuit’s layout. LLC can operate at either the gate or the transistor level, although the gate level is preferred. It is similar to other graph-isomorphism-based tools, hut incorporates some important improvements. The most important of these i...

As energy efficiency becomes a paramount issue in this day and age, reversible computing may serve as a critical step towards energy conservation in information technology. The inputs of reversible computing elements define the outputs and vice versa. Some reversible gates such as the Fredkin gate are also universal; that is, they may be used to produce any logic operation. It is possible to fi...

It is simplest in design and a powerful technique to implement reversible logic. A systema...

The implementation of a low power logic based asynchronous circuit with the help of power gated logic. In asynchronous power gated logic (APL) circuit, each pipeline stage was incorporated with efficient charge recovery logic (ECRL) gate; handshake controller and partial charge reuse (PCR) mechanism. The main objective was, to provide a new lower power solutions using power gating (PG) for very...

Abstruct Behavior of basic and complex logic gates using complementary pass-transistor logic (CPL) under various single-stuck faults are investigated. The result shows that all stuck-on faults in the basic CPL gates can be detected by current monitoring, but no logic monitoring is possible. Similarly all bridging faults between gate and source of basic CPL gates can be detected only by current ...

Quantum cellular automata (QCA) have been used widely to digital circuits and systems. QCA technology is a promising alternative to CMOS technology. It is attractive due to its fast speed, small area and low power consumption, higher scale integration, higher switching frequency than transistor based technology. Various QCA circuits, Multivalve Reversible Logic (MVL) Circuit as well as Feynman ...

In this paper, we present the design of All-optical OR logic gate based on 2-D (two dimension) photonic crystals. To realize this, we consider the photonic crystals (PCs) with a square lattice of dielectric rods (refractive index=3.40). These rods are surrounded by air (refractive index=1).First we design the structure using the Finite Difference Time Domain (FDTD) method and in second step, we...
