Apparatus and method for amplifying signal and wireless transmitter using the same |
摘要 |
Provided are a signal amplifying apparatus and method and a wireless transmitter using the same. The signal amplifier includes a polar coordinate converter configured to output an envelope signal and a phase signal by converting a signal to a polar coordinate, a multilevel quantizer configured to output a multilevel quantized signal by quantizing the envelope signal to multiple levels, an amplification state controller configured to control an amplification state using the multilevel quantized signal, and a power amplifier configured to amplify the phase signal according to the controlled amplification state. |
