The proposed modulator with the two-path DCO modulation enables a flexible gain partition for the high-pass and low-pass modulation paths within the DCO and relaxes the DCO nonlinearity with 1-b ΔΣ modulation and embedded finite-impulse response (FIR) filtering. A semi-digital ΔΣ PLL with another FIR filtering in the low-pass modulation enhances PLL linearity with a hybrid loop control. The proposed semi-digital modulator achieves 2.03% RMS EVM with 2 Mb/s GFSK modulation, -132 dBc/Hz phase noise at 3 MHz offset, and -80 dBc reference spur.</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 integrated circuits; FIR filters; UHF oscillators; delta-sigma modulation; digital phase locked loops; modulators; voltage-controlled oscillators; CMOS technology; FIR-embedded DCO modulation; PLL linearity; delta-sigma modulation; digitally-controlled oscillator; finite-impulse response filtering; frequency 2 GHz; high-pass modulation paths; hybrid loop control; low-pass modulation paths; semidigital two-point modulator; size 0.18 mum; CMOS integrated circuits; Finite impulse response filters; Phase locked loops; Phase modulation; Phase noise; Voltage-controlled oscillators; 1-b DCO modulation; Delta-sigma modulation; FIR embedded; GFSK; fractional-N PLL; polar transmitter; semi-digital PLL; two-point modulation;</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'>Microwave and Wireless Components Letters, IEEE</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'>1531-1309</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/LMWC.2015.2400934</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'>7056561</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=1759761' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=1759761</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
