A power amplifier is disclosed. In one embodiment, the power amplifier is
a Class-D Amplifier having a differential pulse width modulator is
disclosed. The differential pulse width modulator has an input for
receiving an input signal, a first output for outputting a first signal
and a second output for outputting a second signal. A difference between
the first signal and the second signal represents the pulse modulated
signal. The differential pulse width modulator further has a comparator
for comparing the first and second output signals. The comparator
switches 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.
