Integrated Circuit Modeling by means of Equivalent Modeling

This Ensuring proper interaction of the electromagnetic field from the radiator in the design of high-speed printed circuit boards is a current task. In order to accurately predict the electromagnetic field established by the radiator, this paper proposes an approach that includes the exact radiator's emission, which is described by some dipole moments developed on the basis of scanning an integrated circuit under the radiator in the near zone. This approach takes into account both the dipole moments and the passive radiator structure, which in turn is included in the two-wave model. Various models have been proposed using numerical methods and the finite element method using dipole moments. An analytical approach has been proposed to estimate the maximum electromagnetic waves emitted from the radiator. An improved model of the dipole moment for integrated circuits has been presented.

I. Introduction

The metal radiator is usually located close to the integrated circuit (IC) which is the main source of electromagnetic interference in the radio-electronic devices (RED) design. As the IC operating frequency increases, the size of the radiator expands, which leads to a significant increase in electromagnetic radiation as a result of heat removal. Therefore, in order to accurately analyze and reduce radiation from the radiator, its structure must be carefully modeled and designed. Electromagnetic fields from a radiator depend both on the radiator structure and its emissions. Given the same radiator structure, if the location or type of propagation is different, then the radiated fields can be completely different. In traditional radiator modeling and studies the most common source model that causes the configuration of the radiator's electromagnetic field is the voltage source between the radiator and the ground plane.
