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.
