Abstract :
This paper reviews efficient amplification techniques, such as a load modulation, an envelope tracking (ET), an envelope elimination and restoration (EER), an outphasing and a digital modulation for signals with high peak-to-average power ratio (PAPR). Implementations of these techniques in the state-of-art CMOS power amplifiers are compared.
