Traditionally, energy efficiency aspects have been included in the wireless access network
design space only in the context of power control aimed at interference mitigation and for the …

An envelope-tracking (ET) CMOS power amplifier (PA) is fabricated using a 0.18-μm CMOS
process. The module containing the supply modulator, the PA, and the output transformer is …

This book provides a comprehensive view of green communications considering all areas of
ICT including wireless and wired networks. It analyses particular concepts and practices …

The purpose of this invited paper is to give readers a comprehensive and critical overview
on how to extract equivalent‐circuit models for GaN HEMTs, which are the preferred devices …

The Fifth-Generation new radio (5G NR) services that started in 2020 in Japan use a higher
peak-to-average power ratio (PAPR) of a modulated signal with a maximum bandwidth of up …

Featuring high bandwidth and high efficiency, the switch-linear hybrid envelope tracking
(SLH-ET) power supply has been gaining considerable attentions. This paper proposes a …

Envelope tracking (ET) techniques have been used to improve the efficiency of power
amplifiers in wireless communication systems. The switch-linear hybrid (SLH) ET power …

Achieving fast wireless access speeds in an already restricted bandwidth (as the frequency
spectrum is a finite resource) necessitates highly spectrally efficient communications …

As wireless communication standard continues to evolve accommodating the demand of
high data rate operation, the design of radio frequency (RF) power amplifier (PA) becomes …
