高速低相位噪声VCO设计

Design of A High Speed Low Phase Noise VCO

压控振荡器已经成为当今时钟恢复电路和频率合成电路中不可缺少的组成部分。本文分别从压控振荡器的振荡频率和相位噪声两个角度 ,详细阐述影响 VCO性能的因素 。

Voltage controlled oscillators are integral parts of clock recovery circuits and frequency synthesizers. This paper presents a study of VCO from two points of view-generated frequency and phase noise and one new buffer topology that achieves higher frequency and lower phase noise.
