Timing Optimization is one of the most important objectives of the designer in the Modern VLSI world. Memory elements play a vital role in Digital World. The basic memory elements of designer considerations are Latch and flip flop. In this paper, we analyze the design of Single-bit Flip flop (SBFF) and made performance comparison over the Multi-bit Flip-flop (MBFF). For improving Flip flop perf...

In existing flip-chip LED simulations, the light extraction efficiency is related to multiple quantum well (MQW) metal reflector distance because of optical interference. We calculate contrast using several typical intensity distributions among QWs in MQW. The coherence obtained analytically. When luminosity each QW equal, ∼0, meaning incoherent, contrary traditional studies. spatial important ...

This paper studies the chromatic number of the following four flip graphs (under suitable definitions of a flip): • the flip graph of perfect matchings of a complete graph of even order, • the flip graph of triangulations of a convex polygon (the associahedron), • the flip graph of non-crossing Hamiltonian paths of a convex point set, and • the flip graph of triangles in a convex point set. We ...

Introduction Quantitative MR techniques such as variable flip angle (VFA)[1] , DESPOT1 [2], quantitative T 2 [3] etc. rely on the accuracy with which the true flip angle is known. Although spatial inhomogeneity of flip angles is expected at high fields (>1.5T) due to B1 field inhomogeneities and uneven slice profiles, accurate estimates of true flip angle are important even at lower field stren...

This paper enumerates a low power, high speed design of flip-flop having less number of transistors. In flip-flop design only one transistor is being clocked by short pulse train which is known as True Single Phase Clocking (TSPC) flip-flop. The true single-phase clock (TSPC) is common dynamic flip-flop which performs the flip-flop operation with little power and at high speeds. In this paper, ...

This paper provides the initial threshold to building of more complex system having reversible sequential circuits as a primitive component and which can execute more complicated operations using quantum computers. The reversible circuits form the basic building block of quantum computers as all quantum operations are reversible. The important reversible gates used for reversible logic synthesi...

Death receptors trigger apoptosis by activating the apical cysteine proteases caspase-8 and -10 within a death-inducing signaling complex (DISC). c-FLIP (cellular FLICE inhibitory protein) is an enzymatically inactive relative of caspase-8 and -10 that binds to the DISC. Two major c-FLIP variants result from alternative mRNA splicing: a short, 26-kDa protein (c-FLIP(S)) and a long, 55-kDa form ...

Putting a different spin on photonics: Spin-injected vertical-cavity surface-emitting lasers (Spin-VCSELs) with strong anisotropies are important in particular for ultrafast and terahertz applications, but the field is being held back part because of lack sufficiently predictive physical models. This study uses temporal coupled-mode theory transfer-matrix formalism to make progress by extending...

The choice of flip-flop technologies is an essential importance in design of VLSI integrated circuits for high speed and high performance CMOS circuits. The main objective of this project is to design a Low-Power Pulse-Triggered flip-flop. Flip-flops are the major storage elements in all SOC’s of digital design. They accommodate most of the power that has been applied to the chip. Flip-flop is ...
