PDN Impedance, Ground Bounce, and Jitter: Where SI and PI Meet

Power integrity is essential in high-speed PCB design, but power integrity problems can often be overlooked. Sometimes, designers may not realize that their custom STM32 microcontroller board exhibits some of the same power integrity problems as a PCB with a high-speed FPGA. In some cases, the design will operate just fine, until you try to put the board through EMC testing and receive a failing result.
