When time-varying (AC) signals travel in the transmission lines of a board, state-changing electric and magnetic fields are present. These fields, when not controlled, are the source of noise and... [more]
Technical sessions at conferences often emphasize the latest techniques and technologies, but those classes are often too in-depth for a novice designer, and don’t speak to the questions from the... [more]
When designing a PCB, the signal routing and its return are critical to the circuit working properly. Great care is usually given to routing the signals, but often the return portion is the last... [more]
High frequency PCB designs carry a unique set of challenges due to concentration of signal power in a narrow bandwidth. To design high frequency interconnects, designers must consider an entire... [more]
