Kertas kerja ini membentangkan pengayun terkawal voltan (CR-VCO) pembezaan arus yang digunakan semula dengan penggunaan kuasa rendah dan hingar fasa rendah menggunakan teknologi CMOS 7-µm. Kuasa keluaran CR-VCO ini dipertingkatkan dengan menggunakan teknik trifilar-transformer-feedback. Bunyi fasa yang lebih rendah dicapai dengan ayunan voltan yang lebih simetri hasil daripada keseimbangan arus pensuisan yang lebih baik. Pada voltan bekalan DC 0.18-V, pelesapan kuasa hanya 1.5 mW. Jumlah julat penalaan ialah 3.4 GHz (1.4%) kerana voltan penalaan berjulat dari 17.9 V hingga 0 V. Bunyi fasa optimum ialah sekitar -1.8 dBc/Hz pada offset frekuensi 117.3 MHz daripada frekuensi tengah 1 GHz. Kuasa keluaran yang sepadan adalah sekitar -7.07 dBm. Bagi CR-VCO yang dicadangkan, angka merit yang dikira, fom and fomT , ialah -188.9 dan -193.9 dBc/Hz, masing-masing.

Abstract: This paper presents a 7 GHz differential current-reused voltage-controlled oscillator (CR-VCO) with low power consumption and low phase noise using 0.18-µm CMOS technology. The output power of this CR-VCO is enhanced by utilizing a trifilar-transformer-feedback technique. The lower phase noise is achieved by the more symmetric voltage swings resulting from the improved balance of switching current. At a 1.5-V DC supply voltage, the power dissipation is only 3.4 mW. The total tuning range is 1.4 GHz (17.9%) as the tuning voltage ranges from 0 V to 1.8 V. The optimum phase noise is around -117.3 dBc/Hz at a frequency offset of 1 MHz from the center frequency of 7.07 GHz. The corresponding output power is around -6.8 dBm. For the proposed CR-VCO, the calculated figures-of-merit, FOM and FOMT , are -188.9 and -193.9 dBc/Hz, respectively.
