This article presents the derivation of the radiated far fields from a Hertzian dipole antenna above the ground plane using image theory.

It is now well known that testing for CDM ESD evaluation is becoming a bigger challenge. An alternate approach called capacitively coupled transmission line pulsing (CCTLP) offers advantages over standard field-induced CDM testing.

In large systems, such as big cabinets housing numerous electronic components, employing the near-field probe method can be time-consuming and, depending on the voltage level, potentially unsafe (for instance, when dealing with high-voltage circuits requiring isolation). In such scenarios, an alternative approach is necessary.

The Banana Skin columns were compiled by Keith Armstrong, of Cherry Clough Consultants Ltd, from items he found in various publications, and anecdotes and links sent in by the many fans of the column.

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

The ESDA technology roadmap is written to support and guide the daily work of ESD and latch-up experts in the worldwide industry and academia.

ANSI Z535.6 is a standard developed by ANSI specifically focusing on the inclusion of safety information in product manuals and other related materials to enhance user understanding and safety.

This article evaluates the impact of decoupling capacitors and trace length on radiated 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.

The behavior of ultra-high-speed interfaces is complex, involving fast-rise time waveforms and on-die transient phenomena that cause device failure at lower CDM levels.
