A 24GHz Transformer Coupled CMOS VCO for a Wide Linear Tuning Range
In this paper, a 24 GHz transformer-coupled VCO is presented for a wide linear tuning range in the 0.13-μm CMOS process. The measured results of the proposed VCO show that the center frequency is 23.5 GHz with 7.4% frequency tuning range. The output frequency curve has wide linear tuning region (5.5%) at the middle of the curve. Also, the VCO exhibits good phase noise of −110.23 dBc/Hz at an of...

متن کاملWide Tuning Range LC-VCO Using Variable Inductor for Reconfigurable RF Circuit
This paper presents a novel wide tuning range CMOS Voltage Controlled Oscillator (VCO). VCO uses an on-chip variable inductor as an additional variable element to extend the tuning range of VCO. The fabricated variable inductor achieves the variable range of 35%. The VCO was fabricated using 0.35 μm standard CMOS process, and can be tuned continuously from 2.13 GHz to 3.28 GHz (tuning range of ...
متن کاملA Ku-Band Low-Phase-Noise Wide-Tuning-Range VCO in SiGe BiCMOS Technology
—In this paper, design and fabrication of a Ku-band voltage-controlled oscillator (VCO) using commercially available 0.18 μm SiGe BiCMOS technology is presented. To achieve the low phase noise, the VCO employs a gm-boosted configuration which is a combination of cross coupled VCO and balanced Colpitts VCO, and the VCO simultaneously achieves wide tuning range. The tested results show that the ...
