PCB设计

Previously, I posted about designing a simple DC brushed motor controller using a single IC. While it’s a relatively simple

Length matched lines in a PCB Take a look at two signal readouts on an oscilloscope, and you can see

Do you know the transmission line critical length for these traces? Whether you are working with digital or analog signals

The image above shows a snapshot of results from an EMC test under CISPR requirements (U.S. uses FCC certification requirements)

Signal integrity analysis and measurements go hand-in-hand I remember the first time I— back in my days of working with

We often write about signal integrity and power integrity around here, but there is one area where we sometimes fall
