Due to the increasing frequency of digital and/or analog signals the problem of radiation has become of serious concern to manufacturers and designers of electronic products. One of the most important aspects of 'electromagnetic compatibility' (EMC) is the compliance with radiation constraints (CISPR, FCC). Basically all eeects related to scatterers must be taken into account in order to predic...

A simple analytical model to predict the DC MOSFET behavior under electromagnetic interference (EMI) is presented. The model is able to describe the MOSFET performance in the linear and saturation regions under EMI disturbance applied to the gate. The model consists of a unique simple equivalent circuit based on a voltage dependent current source and a reduced number of parameters which can acc...

This paper presents a comprehensive full-wave analysis of packaged nonlinear active microwave circuits by applying the extended finite-difference time-domain (FDTD) method. Based on the approach of using equivalent sources, the device–wave interaction is characterized and incorporated into the FDTD time-marching scheme. As a consequence, analysis of linear and nonlinear properties, including ha...

With the increase of electrical/electronic equipment integration complexity, the electromagnetic compatibility EMC becomes one of the key points to be respected in order to meet the constructor standard conformity. Electrical drives are known sources of electromagnetic interferences due to the motor as well as the related power electronics. They are the principal radiated emissions source in au...

The use of advanced technologies such as FinFETs enables higher levels of integration, allowing designers to pack more functionality into a single SoC — functions that were once on separate components such as GPS, graphics, computers, phone, RF, etc. These devices operate at lower supply voltages, reducing the available noise margin. At the same time, these devices drive more current and are pa...

Switch mode power supply (SMPS) is good selection for power supplies of Unmanned Aerial Vehicle (UAV), which is one of the most important interference sources of UAV. The power switches with their high dv/dt and di/dt switching slopes are the sources of electromagnetic interference (EMI). In this paper, a variable frequency modulation technology of the forward converter of UAV is presented, whi...

In the past, large external filters and shielded cables were the accepted ways to address EMI/EMC (electromagnetic interference or electromagnetic compatibility) in audio/video products. These methods added cost, adversely affected performance, and increased the size of the end product. As these products have decreased in size and evolved into the modern audio/video players, the solutions have ...

This paper investigates the negative effects of electromagnetic interference (EMI) due to fast switching power devices (high dv/dt and di/dt) used in power electronic converters and industrial equipment. Mitigation techniques have been explored to reduce EMI noise effectively. Remedial measures to reduce the risk of equipment malfunction and health risk due to EMI have been explored. In this pa...
