The authors evaluate the impact of capacitors and trace length on conducted emissions.

This column describes the operation of an ideal difference amplifier. It is shown that an ideal difference amplifier (with no resistance mismatches) eliminates the common mode portion of the input voltage and amplifies only the differential mode portion of the input voltage.

This article describes a laboratory experiment that shows the impact of the decoupling capacitors and a PCB trace length on the signal integrity in a CMOS inverter circuit.

This is the third article of a three-article series devoted to the correlation between the insertion loss and input impedance of passive EMC filters.

This is the second of a three-article series devoted to the correlation between the insertion loss and input impedance of passive EMC filters. This article focuses on π and T filters.

This is the first article of a three-article series devoted to the correlation between the insertion loss and input impedance of passive EMC filters.

This is the second article of a two-article series devoted to the return current distribution in a PCB microstrip line configuration.

This is the first article of a two-article series devoted to the return current distribution in a 2-layer FR-4 PCB microstrip line configuration with a solid reference plane.

This article presents the derivation of the far-field criterion for two fundamental wire-type antennas: electric (or Hertzian) dipole and magnetic dipole.

This article explains how to use a Smith Chart to determine the input impedance to transmission line at a given distance from the source or the load.
