A review on techniques and modelling methodologies used for checking electromagnetic interference in integrated circuits

Abstract

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Conducted electromagnetic interference mitigation in super-lift Luo-converter for electric vehicle applications

“…While S is ON, the gross currents flowing through the inductor and capacitor equals the input current I in . During S is OFF, the input current equals the capacitor current I C1 and the inductor current i L1 , as shown in ( 4) to (6).…”

“…But the connection of cables for input as well as output through sockets may reduce the effectiveness of EMI shielding [5]. In switchedmode power supplies (SMPS), a metal packaged case has been used to cover the entire assembly to mitigate the EMI, but the additional cost is required, and there are also some possibilities of EMI leakage through some other accessories like the display unit, cable, and light-emitting diode (LED) lights [6]. The next popular method among the researchers is the randomization technique, which varies the width or position of the pulse randomly.…”

A comparison statement on DCPWM based conducted EMI noise mitigation process in DC-DC converters for EV

“…Due to the above-said reasons, electromagnetic interference (EMI) has been generated and it should be carefully mitigated. Electromagnetic compatibility (EMC) defines a limitation of EMI noise that is generated or radiated from the electronic devices-based circuits when operating at high frequency for the DC-DC conversion process [1], [2]. The classifications of EMC are shown in Figure 1.…”

Improved field uniformity in EMC chamber for 6G communication

“…For example, the maximum speed for 6G communication could reach up to 1,000 Gbps with a wireless delay of 100 microseconds. This would be 50 times faster than 5G communication, and the wireless delay would be reduced to 1/10 th of that of 5G communication [1]- [3]. Advanced countries and companies worldwide are actively researching nine key technologies, including Tbps wireless communication, 3D mobile communication, intelligent wireless access, THz RF components, THz frequency, Tbps optical communication, 3D satellite communication, end-to-end ultra-precision networks, and intelligent mobile core networks.…”
