Abstract: In accordance with embodiments of the present disclosure a control circuit may include at least one input for monitoring a respective signal for each of a plurality of amplifiers, an output for outputting at least one control signal for controlling a power supply level of the single signal-variant power supply configured to deliver electrical energy to the plurality of amplifiers, and decision and control logic. The decision and control logic may be configured to monitor the respective signals for each of the plurality of amplifiers and, based on the respective signals, and a respective requirement associated with each of the plurality of amplifiers, setting a power supply level of the single signal-variant power supply and outputting the at least one control signal to control the power supply level such that the respective requirements are satisfied.
