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 ...

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 ...

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 ...
