The Class-C differential VCO is implemented in TSMC 0.18 μm bipolar-complementary-metal-oxide-semiconductor (BiCMOS) process. The measured phase noise is −124.8 dBc/Hz at 1 MHz offset frequency from 2.48 GHz carrier while consuming 2.64 mW power from a 0.8 V supply. Tuning range of VCO ...
A wide tuning range low phase noise phase-locked loop (PLL) frequency synthesizer based on Class-C voltage-controlled oscillator (VCO) for IEEE 802.11ah is presented. Feedback loop technique is adopted to provide dynamic gate bias to the core transistors of the Class-C VCO, guaranteeing robust...

A 0.3 THz VCO using gm-enhanced technology in 55 nm CMOS A power combined terahertz (THz) voltage-controlled oscillator (VCO) is proposed to increase the output power. Based on the traditional transformer-feedbac... H Fu,Q Song,K Ma - 《Microwave & Optical Technology Letters》 被引量: ...
A SiGe BiCMOS push-pull class-C VCO operating at 17 GHz and making use of only npn transistors is presented. A magnetic transformer is used to set positive feedback around a common-collector differential pair and implement the push-pull operation. This allows to halve the bias current for a...

A High-Swing Class-C VCO with Amplitude Feedback Loop for Low Phase Noise and Robust Start-Up A novel high-swing Class-C VCO with an amplitude feedback loop is presented. The amplitude feedback loop is used to ensure the start-up of the VCO which al... Q Liu,YB Gan,TC Ye - 《...
Concurrently, an auxiliary -gm NMOS only class-B oscillator is incorporated to mitigate the start-up issue of the class-C VCO. At the center frequency of 2.45 GHz, the proposed VCO achieves a power consumption of 1.73 mW, phase noise of -120 dBc/Hz at the 1-MHz offset, and a figure...
2、VCO输出电压幅度计算有两个限制,一个是电流*寄生电阻,一个是MOS管本身的限幅特性。工作在两个限制的临界可以获得最优的相噪--功耗平衡。 3、可以在pnoise仿真后选result-print-noise anlysis下看输出报告,确定每个管子的噪声影响。 4、增加栅极反馈电容可以加快起振,增大输出幅度,改善相噪。
