Since i wanna simulate a diff vco, how to connect the fudemental freq output port and the reference port?
I have referred to the diff vco example in the spectreRF user's guide & connected one current pulse to the reference port,but the fundemental freq i have got differ from the freq i designed.If i changed the rise time of the current pulse,different fundemental freq i got,so how can i?
who can tell me how to set up the right scheme vco simulation in cds?thx
