摘要

测量装置包括安装在微米控制定位器上的金属板探头，用于量化周围对压控振荡器(VCO)特性的影响。在LC-VCO的电感器周围加金属环屏蔽，并在电感器下方放置元器件，减小电路面积，降低了VCO性能对周围环境的敏感性。应该可以在振荡器的顶部加入一个金属板作为封装的一部分，以保护VCO免受周围环境的影响，同时对振荡器性能产生可容忍的影响。

Frequency Sensitivity of Integrated Oscillators to Nearby Conductors

A measurement setup including a metal plate probe mounted on a micrometer-controlled positioner is used to quantify the effects of surrounding to voltage-controlled oscillator (VCO) characteristics. Including a metal ring shield around the inductor of LC-VCO and placing components underneath the inductor to reduce the circuit area lower the sensitivity of VCO performance to surroundings. It should be possible to incorporate a metal plate on top of the oscillator as part of packaging to shield the VCO from the surrounding with tolerable impact to the oscillator performance.
