A Class D amplifier receives an input signal and includes a ramp generator that generates a ramp signal and an inverted ramp signal. A signal generator generates a first signal when the ramp signal or the inverted ramp signal transitions from less than the input signal to greater than the input signal. The signal generator generates a second signal when the ramp signal or the inverted ramp signal transitions from greater than the input signal to less than the input signal. An output stage drives current through a load based on the first and second signals.
