On-chip inductance is becoming increasingly important as technology continues to scale. This paper describes a way to characterize inductive effects in interconnects. It uses realistic test structures that study the effect of mutual couplings to local interconnects, to random lines connected to on-chip drivers, and to typical power and ground grids. The use of parameters to characterize the ind...

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...

Ever increasing circuit density, operating speed, faster on-chip rise times, use of low resistance Copper (Cu) interconnects, and longer wire lengths due to high level of integration in VLSI chip designs, have necessitated the need for modeling of wire inductive (L) effects which were ignored in the past. In this paper we will review different approaches of modeling the on-chip wire inductance,...

We model s-wave and d-wave disordered granular superconductors with a three-dimensional lattice of randomly distributed Josephson junctions. The nonlinear ac resistivity rho(2) of these systems was calculated using Langevin dynamical equations. The current amplitude dependence of rho(2) at the peak position is found to be a power law characterized by exponent alpha, which is not universal but d...

A new one-dimensional (1-D) defected ground unit lattice is proposed in order to improve the effective inductance. Increasing the effective inductance makes it easy to control the cutoff frequency characteristics. The proposed periodic defected ground structure (DGS) provides the excellent cutoff and stopband characteristics. In order to show the improved the effective inductance, three DGS cir...

The Low Current Pulser generates up to a 30 kV potential difference between the wire holder’s anode and cathode. This voltage drops across the specimen and is supported by a combination of the wire’s resistance and the holder’s inductance. A typical load may have 2Ω resistance and 50 nH inductance. Voltage and current are measured with each shot. Current is recorded using a rogowski coil and vo...

We consider the inductance coefficient for a thin toroidal inductor whose thickness depends on a small parameter ε > 0. An explicit form of the singular part of the corresponding potential u is given. This allows to construct the limit potential u (as ε → 0) and an approximation of the inductance coefficient L. We establish some estimates of the deviation u − u and of the error of approximation...

Using a thermal sample of laser-cooled rubidium atoms, we have constructed a neutral-atom circuit analogous to an electronic capacitor discharged through a resistor. The atoms are confined using what we call a free-space atom chip, an optical dipole trap created using a generalized phase-contrast imaging technique. We have also calculated theoretical values for the capacitance and resistance, w...
