After the critical circuits, we like to examine the printed-circuit board (PCB) stackup. Like the schematic, board stackup decisions are often made prior to routing and placement, so this is a good ...

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 ...

Most every device and electronic piece of equipment is outfitted with a printed circuit board (PCB), including smartphones, TVs, appliances, and more. You know the composite. The boards are laminated ...

This video explains how resistors function and how Ohm’s Law defines the relationship between voltage, current, and resistance in electronic circuits. Resistors are passive components used to control ...

Operational amplifiers are a basic component that are discussed in most analog electronics text books. Their origins are primarily military and Walt Jung provides a very thoroughly researched history ...

The topic of electricity often poses difficulties for many secondary school students in physics lessons. Researchers have now developed and empirically evaluated a new, intuitive curriculum as part of ...

AutomationDirect announces the release of a new White Paper, “Basic Pneumatic Circuits”, which discusses common pneumatic circuits that can be used alone or as building blocks in larger pneumatics ...

Courtesy of www.MikeHolt.com. Based on the 2020 NEC. Class 2 circuits are limited to voltage and current values that don’t (usually) present a shock or fire hazard. The power supply for a Class 2 ...

LTSpice is a tool that every electronics nerd should have at least a basic knowledge of. Those of us who work professionally in the analog and power worlds rely heavily on the validity of our ...
