Hi all,
I am currently simulating the phase noise of a current-controlled oscillator (beat frequency 1GHZ).
As explained in the spectreRF docu, I adjust the
reltol, vabstol and iabstol values so that my beat frequency shows the demanded accuracy.
For the pnoise simulation two additional parameters can be specified: relative harmonics and maximum sidebands.
*relative harmonics: docu says use a reasonable numer (e.g 10). But in our simulations I see a hugh difference if I increase this value up to e.g. 40??
*maximum sidebands: docu says to start e.g. with 7 an increase this value up to the point when the pnoise settles.
Can anybody explain the meaning of both parameters?!
Exist a procedure to find the "optimal/realistic" setting for both parameters to assure a certain simulation accuracy
Thx
