A Compact Size Low Power and Wide Tuning Range Vco Using Dual-Tuning Lc Tanks

Abstract: A novel 12 GHz VCO designed and fabricated in a 0.18 µm SiGe BiCMOS technology is presented. Strongly magnetic coupled dual LC tanks with fixed and tunable capacitive elements are introduced to extend tuning range and improve phase noise. By hybrid using of varactor tuning, loaded transformer tuning and switched capacitor tuning, the proposed VCO achieves a wide tuning range of 4.3 GHz (36%) and output power of −9 dBm with only 4.5 mW power consumption and only 0.17 mm 2 chip area.

“…Figure 2 shows the schematics of the differential cross-coupled LC-VCO [4][5][6]. Since the g m of CMOS and HBT devices are both large enough at the oscillator frequency of 21 GHz in 0.13 µm processes; CMOS devices have the advantages of lower saturation voltage (V sat ) and better linearity over HBTs, thus NMOS is more suitable for supplying sufficient output voltage swing to drive the next stage.…”
