You're probably familiar with the old-fashioned strings of holiday lights that go out completely if one bulb burns out. Although these lights cause hours of frustration during the holidays, they also ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

For reliability, designers must create flex circuits that are neither too thick nor bend too much. • Every flex circuit has a neutral-bend axis. • Smaller circuit thickness reduces the risk of damage ...

SMPS is the abbreviation of switching mode power supply, a kind of high-frequency power conversion device and a power supply device. Its function is to convert a level of voltage to the voltage or ...

Last, but not least, we like to look at the I/O (Input/Output) circuits during EMI circuit board reviews. As a port of entry for external currents, I/O circuits are particularly vulnerable to threats ...
