In this paper, we propose a new exact closed form mutual inductance equation for on-chip interconnects. We express the mutual inductance between two parallel rectangular conductors as a weighted sum of self-inductances. We do not place any restrictions on the alignment of the two parallel rectangular conductors. Moreover, they could be co-planar or reside on different layers. Most important, ex...

We present an advanced algorithm for an extraction tool that computes inductances of interconnect structures. As already pointed out in [I] the pursued energy concept leads to a 6-fold integral which can also be evaluated by use of the Monte Carlo method. Classical implementation of the Monte Carlo method, where the whole geometry has to be hunted for the associated element loses efficiency. Ou...

This paper presents the results of investigations on a planar sandwich air-gapped transformer with two different winding configurations. Experimental results of the coil self inductances, voltage ratio versus frequency, and the numerical results for the magnetic flux and eddy-current distributions are presented. It is shown that the voltage ratio and turns ratio are not equivalent and that the ...

The expected high penetration of battery chargers for electric vehicles (EV) in electric networks is foreseen as a potential problem for power quality. Battery chargers are nonlinear devices that inject harmonic currents and pollute network voltages. Thus, their harmonic emissions must be analyzed and reduced by harmonic mitigation techniques to avoid future problems. This paper analyzes and re...

In this paper we consider linear, lumped, finite networks composed of interconnections of time-variable and passive resistances, capacitances, inductances ~ gyrators and transformers. We assume an impedance matrix port description of the network is given and solve the problem of synthesizing the impedance, that is, we determine a set of passive elements and a scheme of interconnection which yie...

Two new general immittance converter (GIC) JFET configurations for the realization of voltage-controlled impedances (VCI’s) are proposed. Compared with previously reported structures, the circuits exhibit wide dynamic range and low distortion properties that are frequency independent, even for nonresistive VCI’s. We consider the influence of op-amps frequency dependent gain and derive condition...
