Question: Suppose the VCO of Fig. 8.25(a) employs varactors whose capacitance is given by Cvar = C0(1 + α1V + α2V2), where V denotes the gate-source voltage. Assume complete current steering and a low-frequency noise current of In 5 Im cos ωmt in ISS.

(a) Determine the AM noise resulting from In.

(b) Determine how the average value of the varactor capacitance varies with In.
