Columns

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.

This article explains the operation of a balun that transforms an unbalanced antenna structure into a balanced one.

ESD models may be used for simulating on-chip integrated circuits or system (board) level circuits with discrete electronic components like diodes, TVS devices, and bipolar junction transistors (BJTs).

Between WEEE, RoHS, REACH and other environmental directives, regulatory compliance labels for handling and disposing of certain products is less intuitive than it seems.

We are proud to carry on the tradition of sharing Banana Skins for the purpose of promoting education for EMI/EMC engineers.

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

TLP ideas are helpful in understanding CDE, but it is an imperfect analogy

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.

When measuring signals in electronic circuits some times what you see on the screen is not what you have in the circuit. Parasitic couplings, mismatching, noise pickup, and many other anomalous effects can give you the wrong picture of your problem.
