| 摘 要： | A differential complementary LC voltage controlled oscillator(VCO) with high Q on-chip inductor is presented.The parallel resonator of the VCO consists of inversion-mode MOS(I-MOS) capacitors and an on-chip inductor.The resonator Q factor is mainly limited by the on-chip inductor.It is optimized by designing a single turn inductor that has a simulated Q factor of about 35 at 6 GHz.The proposed VCO is implemented in the SMIC 0.13μm 1P8M MMRF CMOS process,and the chip area is 1.0×0.8 mm~2.The free-running frequency is from 5.73 to 6.35 GHz.When oscillating at 6.35 GHz,the current consumption is 2.55 mA from a supply voltage of 1.0 V and the measured phase noise at 1 MHz offset is -120.14 dBc/Hz.The figure of merit of the proposed VCO is -192.13 dBc/Hz.
