The LC-tank oscillator exhibits a significant reduction in area such that it is comparable in size to conventional ring oscillators (ROs) while still retaining its salient features of excellent phase noise and low sensitivity to supply variations. The oscillator incorporates an ultra-compact split ...

As a result, it is shown that increasing of tail current and LC tank quality factor decreases the phase error. Derived equations show that the phase error can be cancelled and even controlled by adjusting bias currents. To evaluate the proposed analysis and consequent designed QO, a 5.5 GHz ...
This dissertation focuses on high-performance LC-tank CMOS VCO design at 2 GHz. The high-Q inductors are realized using wiring metal lines in advanced packages. Those inductors are used in the resonator of the VCO to achieve low phase noise, low power consumption, and a wide frequency tuning...
最基本的相位噪声理论由Leeson在1966年提出[4], 揭示了LC-tank的Q值和寄生电阻对VCO相位噪声的影响。该理论非常简明, 通过对理想压控电流源和Q值固定的LC-tank构成的harmonic balance仿真即可验证。此后, Cranincks在文献[5]中解释了电路中的寄生电阻如何引入相位噪声, 这一点同样可以用harmonic balance仿真验证。
An analysis of phase noise in differential cross-coupled inductance-capacitance (LC) oscillators is presented. The effect of tail current and tank power dissipation on the voltage amplitude is shown. Various noise sources in the complementary cross-coupled pair are identified, and their effect on ph...
The inductor-capacitor (LC) tank uses varactors for compensating the disturbances in the center oscillating frequency.
