circuits

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

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.

This article describes the MOV circuit design sequence for the AC mains port overvoltage protection of pluggable type A equipment.

This article investigates the impedance of the three standard passive circuit components (R, L, and C) as well as the frequency response of a PCB trace.

This article explains the creation of a bounce diagram for a transmission line circuit (see [1] for transmission line reflections).

For common-impedance coupling to occur, two circuits must share a current path (with a non-negligible impedance)

The article discusses the behavior of voltage and current waves on a transmission line with different types of loads and explains how to measure the VSWR of an antenna.

Whenever an electronic circuit is first energized, transients occur in current and voltage waveforms. These start-up transients can affect the electrical and thermal behavior of components and circuits with serious reliability, EMI, and random effects. Try to characterize how your circuits start and stop.

Richard Nute examines how transformers behave when subjected to transient overvoltage, both magnetically and capacitively.
