This study presents an inductance capacitance (LC) phase-locked loop (PLL) with a dual voltage-controlled oscillator (VCO) and a noise-reduced low-dropout (LDO) regulator, which was used in four-lane multiprotocol serial link applications. The dual VCO architecture can increase the total frequency-tuning range to ensure that the LC PLL achieves multiprotocol serial link coverage from 8 to 12.5 Gbps. Two switch capacitor array-based LC VCOs have a large frequency-tuning range and small VCO gain. The noise-reduced LDO regulator provides a very low-noise power supply to the VCO. The active area occupied by the proposed LC PLL in UMC 28-nm 1P10M complementary metal–oxide–semiconductor (CMOS) technology is 0.25 mm2. The phase noise of the VCO at 1 MHz is −108.1 dBc/Hz. The power consumption of the LC PLL with a 1.8-V supply is 16.5 mW.

AbstractWe present a continuously tunable 52-to-67 GHz push–push dual-core voltage-controlled oscillator (VCO) in a 40 nm bulk complementary metal–oxide–semiconductor (CMOS) technology. The circuit is suitable for 60 GHz frequency-modulated-continuous-wave radar applications requiring a continuously tunable ultra-wide modulation bandwidth. The LC-tank inductor is used to couple the two VCO cores. The fundamental frequency of the VCO can be tuned from 26 to 33.5 GHz, which corresponds to a frequency tuning range of 25%. The second harmonic is extracted in a non-invasive way using a transformer. The primary side acts simultaneously as a second harmonic filter. The VCO achieves in measurement a low phase noise of −91.8 dBc/Hz at 1 MHz offset at 62 GHz and an output power of −20 dBm. The VCO including buffers dissipates in the dual-core operation mode 60 mA from a single 1.1 V supply and consumes a chip area of 0.58 mm2.

In this paper, two LC Voltage-Controlled Oscillators (LC-LC-VCO1 and LC-VCO2) are designed using TSMC 65 nm LP/MS/RF CMOS technology. Two arrays, one of which is a 6-bit capacitor array and the other – an array of MOS varactors, provide a wide LC-VCO frequency tuning range. Post-layout simulation results unveiled that at 1.8 V supply voltage the tuning range of LC-VCO1 spans from 5.17 GHz to 6.76 GHz and for LC-VCO2 the range spans from 6.33 GHz to 8.08 GHz. The phase noise at 1 MHz offset frequency is about −123.1 dBc/Hz for LC-VCO1 and −121.6 dBc/Hz for LC-VCO2. The power dissipation at maximum carrier is 30.47 mW for LC-VCO1 and 30.5 mW for LC-VCO2. The layout area is 285×335 μm and 255×305 μm, respectively for LC-VCO1 and LC-VCO2. Straipsnyje nagrinėjami ir projektuojami LC įtampa valdomi generatoriai (LC-ĮVG), plačiai taikomi šiuolaikiniuose daugiastandarčiuose ir daugiajuosčiuose siųstuvuose-imtuvuose. Naudojant TSMC kompanijos 65 nm LP/MS/RF KMOP inte­grinių grandynų gamybos technologiją suprojektuoti ir išanalizuoti du skirtingų dažnio diapazonų LC-ĮVG. Generuojamas dažnis yra valdomas dviem būdais, t. y. galimas apytikslis bei tikslus dažnio nustatymas. Norint apytiksliai nustatyti dažnį naudojamas 6 bitais skaitmeniškai valdomas perjungiamų kondensatorių blokas, o norint tiksliai parinkti valdymą – NMOP varaktorių blokas. Kompiuterinio modeliavimo metu gauti tokie pagrindiniai LC-ĮVG parametrai: valdomo dažnio diapazonas – nuo 5,17 GHz iki 6,76 GHz (LC-ĮVG1) ir nuo 6,33 GHz iki 8,08 GHz (LC-ĮVG2); fazinis triukšmas, esant 1 MHz poslinkio dažniui ir maksimaliam nešlio dažniui: –123,1 dBc/Hz (LC-ĮVG1) ir –121,6 dBc/Hz (LC-ĮVG2); vartojamoji galia, esant maksimaliam nešlio dažniui: –30,47 mW (LC-ĮVG1) ir 30,5 mW (LC-ĮVG2). Suprojektuotų LC-ĮVG1 ir LC-ĮVG2 topologijų plotas yra atitinkamai lygus 0,078 mm2 ir 0,096 mm2.

This study describes a wide tuning-range VCO using tunable active inductor (TAI) topology and cross-coupled pair configuration for radio frequency operation. The TAI used two feedback loops to form a cascode circuit to obtain more degrees of freedom for inductance value. The TAI-VCO was fabricated using a 0.18 μm CMOS technology. The coarse frequency tuning is achieved by TAIs while the fine tuning is controlled by varactors. The fabricated circuit provides an output frequency range from 0.6 to 7.2 GHz (169%). The measured phase noise is from −110.38 to −86.01 dBc/Hz at a 1 MHz offset and output power is from −11.11 to −3.89 dBm within the entire frequency range under a 1.8 V power supply.
