1. A device, comprising:
- a power management module;
a radio frequency (RF) module coupled to the power management module; and
a digital module coupled to each of the power management module and the RF module and configured to dynamically adjust a headroom voltage of the power management module based on one or more RF conditions, wherein the digital module is configured to adjust the headroom voltage at a first rate while the one or more RF conditions are improving relative to a previous RF condition and a second, faster rate while the one or more RF conditions are worsening relative to the previous RF condition,wherein the power management module is configured to receive the adjusted headroom voltage and to convey to the RF module an adjusted supply voltage based at least in part on the adjusted headroom voltage.
