摘要

在给定一组规格的情况下，我们实现了一种用于低相位噪声RF LC CMOS压控振荡器(VCO)自动化设计的优化技术。电磁求解器astic与电路模拟器SpectreRF相结合，可以优化VCO电路参数和电感布局。我们的方法在闪烁噪声区域提供了高达20 dBc/Hz的相位噪声改进，在热噪声区域提供了高达5 dBc/Hz的相位噪声改进。本文还开发了一套用于片上螺旋电感器计算机辅助设计的优化程序。该程序允许设计人员以最大质量因子获得所需电感值的布局。

VCOOPT: a tool for VCO phase noise optimization

We have implemented an optimization technique for the automated design of RF LC CMOS voltage controlled oscillators (VCO) with low phase noise given a set of specifications. The electromagnetic solver ASITIC combined with the circuit simulator SpectreRF allows optimization of the VCO circuit parameters and inductor layout. Our approach gives a phase noise improvement of up to 20 dBc/Hz in the flicker noise region and up to 5 dBc/Hz in the thermal noise region. An optimization program for the computer-aided design of on-chip spiral inductors has also been developed. This program allows the designer to obtain the layout of a required inductance value with a maximal quality factor.
