System- and circuit-level innovations provide low power consumption and reduced circuit complexity. The proposed architecture operates in both the first- and second-Nyquist zones to enable a wide tuning range from a fixed sampling frequency of 3.2 GHz. A fully-integrated on-chip quadrature phase-locked loop (QPLL) allows quadrature phase synchronization between a raised-cosine DAC and a quantizer. Implemented in 0.13 μm CMOS the fully-integrated prototype achieves SNDR values of 50 dB, 46 dB, and 40 dB over a 1 MHz bandwidth at 796.5 MHz, 1.001 GHz and 1.924 GHz carrier frequencies, respectively, with a total power consumption of 41 mW. The measured phase noise of the QPLL is -113 dBc/Hz at an offset frequency of 1 MHz and the reference spur is - 74.5 dBc. The RMS period jitter is 1.38 ps at 3.2 GHz.</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; UHF integrated circuits; analogue-digital conversion; low-power electronics; microwave integrated circuits; phase locked loops; CMOS; bandpass ΣΔ ADC; circuit complexity reduction; circuit-level innovations; first-Nyquist zones; frequency 0.8 GHz to 2 GHz; frequency 1 MHz; frequency 3.2 GHz; frequency 796.5 MHz; fully-integrated QPLL-timed direct-RF-sampling; low power consumption; on-chip quadrature phase-locked loop; power 41 mW; quadrature phase synchronization; quantizer; raised-cosine DAC; reconfigurable bandpass continuous-time ΣΔ RF ADC; second-Nyquist zones; size 0.13 mum; system-level innovations; time 1.38 ps; CMOS integrated circuits; Dynamic range; Jitter; Noise; Radio frequency; Resonant frequency; Sensitivity; Charge pump; SDR; direct sampling RF; direct-RF sigma-delta ADC; finite-impulse response DAC; harmonic-rejection injection-locked oscillator; integer-N phase-locked loop; narrowband programmable LNA; reconfigurable; reference spur;</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'>Solid-State Circuits, IEEE Journal of</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'>0018-9200</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/JSSC.2012.2185530</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'>6156479</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=1454792' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=1454792</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
