Hello all,
Just mentioned a old topic about how to trigger the VCO in simulation. I know it was discussed before in
http://www.designers-guide.org/Forum/YaBB.pl?num=1066188298/7In above post, the suggestion is to add impulse (voltage or current) to 'kick' VCO or play around the initial conditions.
But, I remember there was another simple method (I can't find the post in the forum) mentioned that just setup the
'maxstep' in transient simulation (SpectreRF). e.g. if the frequency of vco is 5 GHz, let the maxstep = 5p. After doing so,
the 'impulse' component isn't necessary and the VCO will start by itself.
Unfortunately, I can't remind the detail of how to setup this 'maxstep' under the operating frequency. Does someone
know this or find the original post? Thank you.
