Claim 17:
18. A system comprising:
one or more amplifiers each having an input, an output and a supply terminal;
at least one multi-level power supply coupled to respective ones of the supply terminals of the one or more amplifiers, each of at least one multi-level power supplies configured to provide a plurality of discrete supply voltages;
a plurality of modulators coupled between the at least one multi-level power supplies and the supply terminals of the respective ones of the one or more amplifiers, the modulators configured to modulate the discrete supply voltages;
a control circuit coupled to provide control signals to the plurality of modulators to modulate the supply voltages provided to the supply terminals of the plurality of amplifiers, wherein the control circuit is configured to provide a time delay to introduce a null frequency into an operating frequency spectrum of the one or more amplifiers; and
one or more delay circuits coupled between the control circuit and respective ones of the plurality of modulators to delay the control signals received by the respective ones of the plurality of modulators.
