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).

Columns

Human-Body Model and Electrostatic Discharge (ESD) Tests

Consider a spherical capacitor consisting of two concentric, conducive spheres separated by a dielectric.

Columns

Alternative Paths of the Return Current

Consider a two-sided PCB with a single trace on top and full copper ground plane on the bottom.

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.

Columns

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.
