摘要

一款完全集成的差分SiGe VCO专为5 GHz无线应用而设计。测量到的相位噪声为-98 dBc/Hz,偏移频率为100khz,偏离5ghz载波。它的调谐范围为12.3%,控制电压从0到3v,优点值大于-180 dBc/Hz,从3v提取的电流为核心5ma,输出缓冲2.2 mA。

A fully-monolithic SiGe differential voltage-controlled oscillator for 5 GHz wireless applications
A fully integrated and differential SiGe VCO was designed for 5 GHz wireless applications. The measured phase noise is -98 dBc/Hz at 100 kHz offset off the 5 GHz carrier. It has a tuning range of 12.3% with a control voltage from 0 to 3 V, and a figure of merit of more than -180 dBc/Hz, The current drawn from 3 V is 5 mA for the core and 2.2 mA for the output buffers.
