In this paper we present a detailed theoretical analysis of lateral and angular misalignment effects in RF coils. Radio-frequency (RF) coils are used extensively in the design of implantable devices for transdermal power and data transmission. A design procedure is established to maximize coil coupling for a given configuration to reduce the effects of misalignment on transmission efficiency. F...

A nH level mutual inductor has been designed and used as the standard impedance for measuring the equivalent inductance of current shunts. A method has also proposed to measure the mutual inductance against the ac voltage standard and current standard at frequencies up to 200 kHz.

This paper introduces a new global-tier interconnect scaling scheme which ensures that inductance effects do not start dominating the overall interconnect performance. It is shown that for unscaled global lines, inductance effects increase as technology scales while for the scaling scheme proposed by ITRS [1], interconnects become extremely resistive and, while inductance effects diminish with ...

With operating frequencies reaching the multi-GHz range, the role of on-chip inductance is becoming increasingly significant. The inclusion of inductance in the interconnect model is particularly necessary in clock distribution networks and also in signal and power lines, which have wide wires and hence low resistance. The principal complexity in the extraction of inductance is that one needs t...

In this paper we present a more accurate method for solving a frequency-dependent inductance of 3-D structures that contains permeable materials. The extracted inductance using the new method is much more accurate than when using the traditional collocation method for no increased cost. Computational results are presented and compared with data to demonstrate the accuracy improvement of the app...

This paper presents a lumped-parameter magnetic model for an interior permanent-magnet synchronous machine. The model accounts for the effects of saturation through a nonlinear reluctance-element network used to estimate the -axis inductance. The magnetic model is used to calculate inductance and torque in the presence of saturation. Furthermore, these calculations are compared to those from fi...

Novel compact expressions that describe the transient response of a high-speed distributed resistance, inductance, and capacitance ( ) interconnect are rigorously derived with on-chip global interconnect boundary conditions. Simplified expressions enable physical insight and accurate estimation of transient response, time delay, and overshoot for high-speed global interconnects with the inclusi...

In this paper, a precorrected-FFT approach for fast and highly accurate simulation of circuits with on-chip inductance is proposed. This work is motivated by the fact that circuit analysis and optimization methods based on the partial element equivalent circuit (PEEC) model require the solution of a subproblem in which a dense inductance matrix must be multiplied by a given vector, an operation...

Previous studies have already introduced a variable active-passive reactance (VAPAR) to be used as virtual inductance in power circuits. Its most remarkable feature of generating a negative virtual inductance can be used to cancel an undesired existing inductance. It has found applications in the rapid power flow control of power systems, for flexible AC transmission systems, where the power fl...

this paper presents developing an analytical model for flux switching motors. the motor is a class of variable reluctance motors that has two windings on stator; a field winding and an armature winding. due to saliency of both stator and rotor poles, accurate modeling is difficult which arises from the nonlinear behavior of the machine. this paper presents a simple model which is able to predic...
