| CONCLUDING REMARKS

Structure-borne vibration is routine for many applications, causing degradation in phase noise performance of several systems. In this article, various design techniques, stabilization methods and precautions are presented for improved phase noise performance. This stabilization approach is verified experimentally to get better phase noise performance under different vibration conditions. This leads to design of a robust and improved PLL phase noise system, that makes it suitable for electronic and airborne warfare applications and other applications where the effects of acceleration or vibration affect the purity of output signal.
