On the use of MOS varactors in RF VCOs IEEE Journals

WebThose varactors were implemented in LC-VCO and a subject to specific comparison in [2], [7], [14]- [16]. It was concluded that the IMOS and A-MOS varactors have better phase … WebA 10 GHz fully integrated Voltage Controlled Oscillator is presented. A 29.7% tuning range is achieved from a 2.5 V power supply. The phase noise is −113 dBc/Hz at 600 kHz and −127 dBc/Hz at 3 MHz. The VCO is implemented in a 0.25 μm 4 metal layer standard CMOS technology. This design will be used to discuss design and layout issues for high … css tab stops

IEEE Journal of Solid-State Circuits 2000,35(6):905-910. … Webswitched binary-weighted capacitors and standard varactors, this VCO achieves a 28% tuning range with a control voltage ranging from 0-2 V, while maintaining a tuning sensitivity of less than 75 MHz/V over its entire frequency range. Compact choke inductors are used in place of resistors to provide a low noise bias point to the varactors. WebThis paper presents two 1.8 GHz CMOS voltage-controlled oscillators (VCOs), tuned by an inversion-mode MOS varactor and an accumulation-mode MOS varactor, respectively. Both VCOs show a lower power consumption and a lower phase noise than a reference VCO tuned by a more commonly used diode varactor. The best overall performance is … css table 高さ 可変
