Aims. Lumped-element kinetic inductance detectors (LEKIDs) are an attractive technology for millimeter-wave observations that require large arrays of extremely low-noise detectors. We designed, fabricated and characterized 64-element (128 LEKID) arrays of horn-coupled, dual-polarization LEKIDs optimized for ground-based CMB polarimetry. Our devices are sensitive to two orthogonal polarizations ...

Frequency-modulated (FM) pulses that function according to adiabatic principles are becoming increasingly popular in many areas of NMR. Often adiabatic pulses can extend experimental capabilities and minimize annoying experimental imperfections. Here, adiabatic principles and some of the current methods used to create these pulses are considered. The classical adiabatic rapid passage, which is ...

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...

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...

SPICA, a Japanese led mission, is part of the JAXA future science program and is planned for launch in 2018. SPICA will perform imaging and spectroscopic observations in the 5 to 210 mm waveband. The SPICA payload features three instruments, one of which, SAFARI, is developed by a European based consortium. SPICA’s distinctive feature is to use an actively cooled telescope down to 4 K. In addit...

This paper presents a novel method for demagnetization fault detection in permanent magnet synchronous machine (PMSM). Demagnetization is common problem existing PMSM which deteriorates the performance and can lead to serious subsequential damages. Unlike most popular based on analysis of currents detecting this type fault, approach proposed analyzes voltage signal non-invasive search coil by m...

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...
