Power amplifier

A Class-D amplifier comprising:

• a differential pulse width modulator having an input for receiving an input signal and having a first output for outputting a first signal and a second output for outputting a second signal, wherein a difference between the first signal and the second signal is the pulse modulated signal output;
• and
• a comparator configured to compare the first and second output signals, the comparator switching both the first and second output signal from a high state to a low state, if both the first and second output signals are in a high state.

A method for driving a Class-D amplifier, comprising:

• generating a first and second output signal, a difference between the first and second output signal representing a differential pulse width modulated signal;
• and
• switching both the first and second output signal from a high state to a low state, if both the first and second output signals are in a high state.

An amplifier circuit comprising:

• a pulse width modulator configured to receive an input signal and provide a first output signal and a second output signal, wherein a difference between the first output signal and the second output signal is a differential pulse modulated signal;
• and
• means for comparing configured to compare the first and second output signals, and switch the first and second output signal from a high state to a low state, if both the first and second output signals are in a high state.
