摘要

采用自组装卷曲圆弹簧三维电感的平衡硅BiCMOS振荡器，峰值Q为40，在100kHz偏置时，与传统平面螺旋电感相比，相位噪声降低了12.3dB。增加一个5/spl mu/m的铜底层将Q提高到85。

Low-noise monolithic oscillator with an integrated three-dimensional inductor

A balanced silicon BiCMOS oscillator using self-assembled curled circular spring 3D inductor with peak Q of 40 reduces phase noise by 12.3dB at 100kHz offset compared to conventional planar spiral inductor approach. The addition of a 5/spl mu/m copper underlayer raises Q to 85.
