The aim of this paper is to present a new method used to calculate the long term stability and drift of a group of standard inductors of the Laboratory of Capacitance and Inductance (Lacin), of the National Institute of Metrology, Normalization and Industrial Quality (Inmetro). Using the concepts of time series and standard error of estimate, we developed an automated system with the objective ...

The dense plasma focus is a discharge powered by capacitor bank. Standard diagnostics include the measurement of time derivative current through and voltage across its connections with Interpretation this diagnostic data often involves some assumptions regarding representation as varying inductance. One characteristic features waveform relatively sharp dip an associated spike. This has been int...

The decreasing deleterious impact inductance accuracy measurements achieved by proper...

The modular toroidal coil (MTC) is composed of several solenoidal coils (SCs) connected in series and distributed in toroidal and symmetrical forms. In this paper, we present an accurate approach for calculation of the mutual and self-inductance between all the SCs of MTC with any arbitrary section. We use Biot-Savart’s and Neumann’s equations to calculate the selfand mutual inductance between ...

This paper introduces an accurate analysis of on-chip inductance effects for distributed interconnects that takes the effect of both the series resistance and the output parasitic capacitance of the driver into account. Using rigorous first principle calculations, accurate expressions for the transfer function of these lines and their time-domain response have been presented for the first time....

The National Institute of Standards and Technology (NIST) watt balance experiment completed a determination of Planck constant in 1998 with a relative standard uncertainty of 87 × 10(-9) (k = 1), concurrently with an upper limit on the drift rate of the SI kilogram mass standard. A number of other fundamental physical constants with uncertainties dominated by this result are also calculated. Th...

This paper presents a fully integrated, reconfigurable inductance, developed for high-speed power system transient stability emulation. Known active inductance topologies are not suitable for this application for two main reasons. Firstly, most active inductors are used at very high frequencies, due to their RF applications, and secondly, the DC characteristics of active inductors lead to a sat...

Advancements in integrated circuit technology have led to an increase in switching speeds of digital circuits. This increase is the primary reason why inductance induced noise (e.g., oscillation, delay, crosstalk) is beginning to cause chips to fail [3]. Thus, we now see a great interest in the inductance associated with on-chip signal lines [2]. Validation and test issues related to capacitive...

The design of high integrity, area efficient power distribution grids has become of practical importance as the portion of on-chip interconnect resources dedicated to power distribution networks in high performance integrated circuits has greatly increased. The inductive characteristics of several types of gridded power distribution networks are described in this paper. The inductance extractio...

This paper shows a new displacement-to-frequency transducer based on the variation of a coil inductance when a magnetic core is partially or completely inserted inside. This transducer is based on a Colpitts oscillator due its low manufacturing price, behavior and immunity to noise. A tank circuit with a configuration in parallel was used because it can be employed at lower frequencies and it e...
