Claim 18:
19. An apparatus, comprising:
a first comparator configured to receive a first ramp and generate a first triggering signal;
a second comparator configured to receive a second ramp and generate a second triggering signal, wherein the first ramp and the second ramp are offset by half a period T;
a pulse-width modulation (PWM) controller configured to generate a first control signal and a second control signal based on the first and second triggering signals;
a ramp generator configured to generate the first ramp and the second ramp;
an analog-to-digital converter (ADC) having an ADC output;
an adder having a positive input, a negative input coupled to the ADC output, and an adder output; and
a voltage controller having an input coupled to the adder output and an output coupled to the ramp generator.
