Hi Brad,
That's correct, therefore I am extracting the signal through the collector so I can use the transistor as a first buffering stage itself. The next thing to consider is then, how to transfer this extracted power to the buffer in an efficient way, and there is when I stumble upon the matching stage between the buffer stage and the collector of the transistor. I think I have to find the large signal output impedance of the oscillator seen at the collector so I can match the input of the buffer to the output of the transistor. The thing is I don't know how to simulate this in Cadence.
Any comment is very useful to me. Thank you.
