Simulating an injection-locked frequency divider
Feb 22nd, 2005, 8:42am
 
Dear all,

I'm trying to simulate a small system containing a VCO

and an injection-locked frequency divider (ILFD).

In this simulation, I created a VCO runing at a frequency

of f_h and created another VCO which is used as the

ILFD runing at half of f_h.

My question is, since the simulation containing two

circuits which run at different frequency,

"How should I select the frequency in the PSS

simulation of SpectreRF" ?

Thank you so much,

Alez

To simulate with SpectreRF the two oscillators must be locked, so that there is only one fundamental frequency, which would be the output of the divider. This is the frequency you give to SpectreRF. Then the other frequency, that of the VCO, appears to be a harmonic of the fundamental.
