EMC Concepts Explained

This article discusses CMOS inverter switching and shows the impact of a decoupling capacitor on the power rail signal integrity and radiated emissions.

This article discusses the creation of a common-mode current in a typical circuit and explains the effectiveness of a common-mode choke on differential-mode and common-mode currents.

This article reviews the decibel units used in EMC laboratory measurements and testing. We begin by defining a decibel (dB) unit and proceed to the EMC specific units for voltage, current, power, and impedance measurements.

Network analyzer measurements require the calibration procedure which utilizes a calibration kit, consisting of a short, open, and a 50 Ω load attachment.

This Part II of the tutorial illustrates the Bode plots’ use in several EMC applications. EMC applications will include the non-ideal models of resistors, inductors, and capacitors, as well as the spectral bounds on digital clock signals.

The importance of Bode plots in EMC cannot be overstated. This Part I of the tutorial discusses the basics of Bode plots construction.

This part II of the RC Snubber topic discusses the systematic and efficient design process and design verification through simulations and laboratory measurements

This is the first of two articles devoted to RC snubber design. In Part I, we discuss the fundamentals of inductive switching and the need for circuit protection.

This article investigates the impedance of the three standard passive circuit components (R, L, and C) as well as the frequency response of a PCB trace.

This article discusses the reflections on a transmission line at the capacitive and inductive loads.
