This paper presents adiabatic flip-flops based on CPAL (complementary pass-transistor adiabatic logic) circuits with energy-recycling output pad cells. The energy-recycling output pad cells for driving adiabatic chips include mainly bonding pads, ESD (electrostatic discharge) protection circuits, and two stage energy-recycling buffers. The adiabatic flip-flops and sequential circuits with energ...

The equation of state for matter with energy density above 2 × 10 gm/cm is parametrized by P = kN , where N is the number density, Γ is the adiabatic index, and k a constant. Using this scheme to generate thousands of models, together with data on neutron star masses, it is found, for a core region with constant adiabatic index, that the central density must satisfy 10 gm/cm < ρc < 10 16 gm/cm,...

Recently, Marzlin and Sanders (2004) demonstrated an inconsistency when the adiabatic approximation was applied to specific, ”inverse” time-evolving systems. Following that, Tong et al. (2005) showed that the widely used traditional adiabatic conditions are insufficient to guarantee the validity of the adiabatic approximation for this class of systems. In this article we explore the origin of t...

The bunching of giant planets at a distance of several stellar radii may be explained by the disruption of the inner part of the disk by the magnetosphere of the star during the T Tauri stage of evolution. The rotating magnetic field of the star gives rise to a low density magnetospheric gap where stellar migration is strongly suppressed. We performed full 3D magnetohydrodynamic simulations of ...

Abstract The polytropic process characterizes the thermodynamics of space plasma particle populations. index, γ , is particularly important as it describes thermodynamic behavior system by quantifying changes in temperature compressed or expanded. Using Wind spacecraft and magnetic field data during 1995 February–2015 December, we investigate evolution 336 interplanetary coronal mass ejection (...

We design an all-dielectric Lüneburg lens as an adiabatic space-variant lattice explicitly accounting for finite film thickness. We describe an all-analytical approach to compensate for the finite height of subwavelength dielectric structures in the pass-band regime. This method calculates the effective refractive index of the infinite-height lattice from effective medium theory, then embeds a ...

Air trench structures for reduced-size bends in lowindex contrast waveguides are proposed. To minimize junction loss, the structures are designed to provide adiabatic mode shaping between lowand high-index contrast regions, which is achieved by the introduction of “cladding tapers.” Drastic reduction in effective bend radius is predicted. We present two-dimensional (2-D) finite-difference time-...

Efficiency of adiabatic circuits is determined by the adiabatic and non-adiabatic losses incurred by them during the charging and recovery operations. Lesser be the losses more energy efficient would be the circuit. In this paper, a new approach i.e., Complementary Energy Path Adiabatic Logic (CEPAL), is presented to minimize power dissipation in quasi static energy recovery logic (QSERL). It o...

-In recent years, low power circuit design has been an important issue in System on Chip (SoC) and VLSI design areas. Adiabatic logics, which dissipate less power than static CMOS logic, have been introduced as a promising new approach in low power circuit design. Adiabatic circuits are those circuits which work on the principle of adiabatic charging and discharging and which recycle the energy...
