FreeLists / si-list / [SI-LIST] How to couple noise to the PDN of oscillator

[Zhangkun <zhang_kun@xxxxxxxxxx>]

Dear all
 
Now we are studying the effect of power noise on jitter. We meet a problem,
how to couple noise to the PDN. For example, we want to couple noise of
25MHz into the PDN of oscillator. However there is impedance dismatch. The
impedance of signal source is about 50ohm and that of PDN is about 0.1ohm.
The energy would be reflected.
 
Any advice would be helpful
 
Best Regards
