This analysis results in practical analytical expressions, which significantly simplify the design and optimization of Class-E PAs. To demonstrate their applicability, the design of a state-of-the-art 2.45-GHz differential cascode Class-E PA in 0.18- CMOS with on-chip dc-feed inductor is presented. By the proposed combination of a dynamic supply voltage and a dynamic cascode bias voltage, high drain efficiency is achieved over a wide power control range, covering from 2.2 up to 20 dBm. At 20 dBm, a power-added efficiency as high as 43.6% was measured. Additionally, fast envelope switching is obtained by adding a single switch to the common-gate nodes of both the Class-E stage and the second driver stage. Measurements show a rise time of merely 2.5 ns and a 73-dB isolation between the on- and off-states. These figures enable ranging applications with submeter accuracy.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>CMOS analogue integrated circuits; UHF integrated circuits; UHF power amplifiers; circuit optimisation; differential amplifiers; driver circuits; inductance; inductors; integrated circuit design; CMOS circuits; Class-E PA design; Class-E PA optimization; PAE; common-gate nodes; complementary metal oxide semiconductor circuits; differential cascode Class-E PA; driver stage; dynamic cascode bias voltage; dynamic supply voltage; fast envelope switching; fast switching class-E power amplifier; finite dc-feed inductance; frequency 2.45 GHz; high drain efficiency; noise figure 18 dB; on-chip dc-feed inductor; power control range; power-added efficiency; size 0.18 mum; CMOS integrated circuits; Inductance; Power amplifiers; Power generation; Switches; Switching circuits; Topology; Cascode; Class E; complementary metal–oxide–semiconductor (CMOS); efficiency; fast switching; loss; output power; power amplifiers (PAs); power control;</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>fLanguage : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>English</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Journal_Title : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Circuits and Systems II: Express Briefs, IEEE Transactions on</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Publisher : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>ieee</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>ISSN : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>1549-7747</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Type : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>jour</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>DOI : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>10.1109/TCSII.2012.2186363</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Filename : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>6152137</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Link To Document : </div><div class='valueDiv leftDirection leftAlign fullRecValueEnglish col-xs-8 col-sm-10'><a href='https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=1448584' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=1448584</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
