1. A method for dynamic tuning of voltage regulators in a computing environment, the method comprising:
determining one or more sampling parameters of an application associated with a downstream voltage regulator; and
dynamically adjusting one or more of a power supply rejection ratio (“PSRR”) and a switching frequency of an upstream voltage regulator based on the one or more sampling parameters of the application associated with the downstream voltage regulator, wherein the sampling parameters include at least a noise level and a workload of the application.
