Classification: CPC H | IPC H

Claim 12:
13. The supply modulator of claim 12, wherein the switching regulator controller comprises:
an operational transconductance amplifier (OTA) configured to output a difference value by comparing a difference between a voltage of the coupling capacitor and the target voltage signal;
a summer configured to sum the difference value and the sensing value to obtain a compensation value;
a compensation comparator configured to compare the compensation value with a reference value to obtain a first comparison value;
a digital-to-analog converter configured to convert an average power signal into a reference voltage signal;
an output comparator configured to compare the reference voltage signal with the output voltage to obtain a second comparison value; and
a multiplexer configured to output one among the first comparison value and the second comparison value to the switching regulator as a switching regulator control signal.
