Title: Why the VCO has high output impedance?
Post by shankey on Aug 22^nd, 2016, 6:41am

Hello everyone,
As we all know VCO has high output impedance, thats why we need buffer at the output of VCO. I am designing LC VCO with cross coupled differential toplogy.

So my question is Why the VCO has high output impedance?
Please help me.
