Automatic Amplitude Control

automatic amplitude control

hey

I am designing a circuit and I need to adjust the value of the varactor. But the problem is that I want to design something which works with not the voltage of a reference node, but with its capacitance. Is it possible?

you apply a reverse voltage to the varactor based on the input and hence the capacitor value changes and this when kept in a voltage divider configuration controls the output amplitude based on the input level....
