i'm trying to use a VCO with LC active inductor but i noticed that there are two ouputs vo+ & vo-.. do i only use one? or is it even viable? thanks in advance
hello, thanks for replying.. but i cant understand why we can't see the output and frequency can you please elaborate?.. i've got a decent oscillation in my simulations or is that not what the actual output is? i'm trying to use it in a PLL as VCO btw
It depends on the DIVIDER, PFD, LO driver circuitry. If they are differential use both, gives advantage for common mode rejection. But if they are single ended, just use one of them.
