Impact of a Trace Length on Capacitor Frequency Response
In this article we investigate the frequency behavior of a ceramic capacitor.
Guard Trace Impact on Crosstalk Between PCB Traces
This article discusses the crosstalk reduction between PCB traces by utilizing a guard trace between the traces and investigating the effect of the guard trace grounding.
Radiated Emissions Measurements: OATS and ALSE Methods
This article is devoted to the radiated emissions measurements. These measurements can be performed either at the Open Area Test Site (OATS) or in an Absorber-Lined Shielded Enclosure (ALSE).
Standing Waves on Transmission Lines and VSWR Measurements
Foundations
Consider the transmission line circuit shown in Figure 1. A sinusoidal voltage source with its source impedance drives a lossless transmission line with characteristic impedance ZC, terminated in... Read More...
Current Probe Measurements in EMC Testing

Conducted Emissions Measurements: Voltage Method
This article describes the voltage method of the conducted emissions measurements.
Topology and Characterization of a DC Line Impedance Stabilization Network
This article discusses the topology and characteristics of a dc Line Impedance Stabilization Network (LISN), often referred to as an Artificial Network (AN).
Human-Body Model and Electrostatic Discharge (ESD) Tests
Consider a spherical capacitor consisting of two concentric, conducive spheres separated by a dielectric.
Spectra of Digital Clock Signals
Reducing the duty cycle (the pulsewidth) reduces the low-frequency spectral content of the waveform, but does not affect the high-frequency content.
Crosstalk Reduction Between PCB Traces
When two circuits are in the vicinity of one another, a signal propagating in one circuit can induce a signal in another circuit, due to capacitive (electric field) and/or inductive (magnetic field) coupling between the circuits. This phenomenon is referred to as crosstalk.
