A common joke in electronics is that every piece of wire and PCB trace is an antenna, with the only difference being whether this was intentional or not. In practical terms, low-frequency wiring is ...

[Ralph] is excited about impedance matching, and why not? It is important to match the source and load impedance to get the most power out of a circuit. He’s got a whole series of videos about it. The ...

The basic concepts underpinning time-domain reflectometry. Difference between frequency- and time-domain analysis. Some applications of TDR measurements. Time-domain reflectometry (TDR) is a technique ...

Most Wi-Fi and Bluetooth designs will appear to work during board bring‐up, even if the antenna feedline has a horrible mis‐match, but then you get to range testing and data integrity ...

Why the power-delivery network is critical in modern power electronics. How integrated voltage regulators can improve the PDN and simplify the PCB design. How IVRs improve power delivery to processors ...
