POWER AMPLIFIER AND METHOD FOR ERROR CORRECTING OF OUTPUT SIGNALS THEREOF

摘要

An amplifier includes a subtracting unit for generating an error signal according to an input signal and an output signal; a noise shaping unit for executing a noise shaping operation on the error signal to produce a noise-shaped signal; a pulse adjustment unit for generating a control signal according to the noise-shaped signal and the input signal; and a power stage for generating the output signal according to the control signal.
