Abstract:
A signal amplifying apparatus, a wireless transmitting apparatus, and a signal amplifying method are provided. The signal amplifying apparatus modulates an envelope signal using a multi-bit quantizer, thereby increasing coding efficiency and tracking optimal supply voltage with respect to envelope variation due to the use of the multi-bit quantizer.
