Claim 16:
17. A method of supporting distributed power management comprising:
configuring a distributed voltage modulation to include a voltage output that outputs the modulated voltage, a voltage amplifier configured to generate the modulated initial voltage, and a voltage offset circuit comprising an offset capacitor coupled between an output of the voltage amplifier and the voltage output and configured to raise the modulated initial voltage by the modulated offset voltage to thereby generate the modulated voltage and a bypass switch coupled between the output of the voltage amplifier and a ground;
receiving the modulated target voltage indicating that the modulated voltage will increase from the present voltage level to the future voltage level, activating the voltage amplifier prior to the start of the upcoming time interval to generate the modulated voltage at the future voltage level subtracted by the modulated offset voltage within the defined temporal limit, opening the bypass switch after activating the voltage amplifier to thereby charge the offset capacitor to increase the modulated offset voltage from the present voltage level to the future voltage level, closing the bypass switch in response to the offset capacitor being charged up to the future voltage level, and deactivating the voltage amplifier after closing the bypass switch; and
receiving the modulated target voltage indicating that the modulated voltage will decrease from the present voltage level to the future voltage level, activating the voltage amplifier prior to the start of the upcoming time interval to generate the modulated voltage at the present voltage level, opening the bypass switch to discharge the offset capacitor to reduce the modulated offset voltage from the present voltage level to the future voltage level, closing the bypass switch in response to the offset capacitor being discharged to the future voltage level, and deactivating the voltage amplifier after closing the bypass switch.
