Classification: CPC H | IPC H

Claim 1:
2. The supply modulator of claim 1, wherein the switching regulator controller comprises:
a plurality of operational transconductance amplifiers (OTAs) configured to output a plurality of difference values by comparing the plurality of voltages and the plurality of reference output voltage signals;
a first multiplexer configured to output a selected different value among the plurality of difference values based the level control signal;
a summer configured to sum the selected 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 second 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.
