In part 12 of Resolving the Signal, we look at a power-supply noise design example to discuss which supplies are most critical when trying to increase a system's PSR. From that example, we offer best practices to maintain low power-supply noise and debugging tips for a system's overall noise performance.

Part 11 of the Resolving the Signal series explores how power supplies contribute to unwanted noise, how to measure and quantify that noise, and how noise ends up impacting system performance.
