A high‐accuracy filtering‐based envelope generation technique for wideband envelope tracking power amplifiers (ET PAs) is proposed to improve PA efficiency with limited envelope bandwidth. It is achieved by optimizing the envelope generation block by employing three generalized rectification functions. The proposed envelope can be obtained by finding the proper coefficients in these generalized rectification...
This paper presents a digitally-controlled highly efficient supply modulator. This supply modulator is implemented as a multilevel converter in series with a linear amplifier. The multilevel converter output which controlled by digital signals is employed to supply the linear amplifier. The digitally controlled strategy and the optimization of the supply levels can make the converter output to approach...
