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

(a) Determine the AM noise resulting from I_n.

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