摘要

本文研究了压控振荡器中的非线性和相位噪声对基于vco的连续时间一阶Delta-Sigma调制器模数转换器性能的影响。通过MATLAB/Simulink模型实现了测试电路，并在Spectre环境中对设计的两个不同的25环压控振荡器进行了数据外推。

Impact of VCO non-linearities on VCO-based sigma-delta modulator ADCs

In this paper, the effects of non-linearities and phase noise in a voltage-controlled oscillator on the performance of VCO-based Continuous Time First-Order Delta-Sigma Modulator Analog-to-Digital Converter are studied. A test circuit was implemented MATLAB/Simulink model and data extrapolated from two different 25-ring VCOs designed and simulated in Spectre environment.
