Classification: CPC G  H | IPC G  H

Claim 11:
12. A distributed voltage modulation circuit comprising:
a voltage output that outputs a modulated voltage comprising a modulated initial voltage and a modulated offset voltage;
a voltage amplifier configured to generate the modulated initial voltage;
a voltage offset circuit coupled between the voltage amplifier and the voltage output and configured to generate the modulated offset voltage based at least on a low-frequency current generated outside the distributed voltage modulation circuit; and
a control circuit configured to:
receive a modulated target voltage indicating that the modulated voltage will change from a present voltage level in a present time interval to a future voltage level in an upcoming time interval;
activate the voltage amplifier prior to a start of the upcoming time interval to increase the modulated voltage from the present voltage level toward the future voltage level when the future voltage level is higher than the present voltage level;
activate the voltage amplifier prior to the start of the upcoming time interval to maintain the modulated voltage at the present voltage level when the future voltage level is lower than the present voltage level; and
cause the voltage offset circuit to change the modulated offset voltage from the present voltage level to the future voltage level within a defined temporal limit from the start of the upcoming time interval and maintain the modulated offset voltage at the future voltage level in the upcoming time interval.
