Assume that the phase noise characteristic of a PLL is being examined. The internal phase noise of the VCO is modeled by the input θn(t), as shown in Fig. P4–35.
(a) Find an expression for the closed-loop transfer function
(b) If F1(f) is the low-pass filter given in Fig. P4–34, sketch the Bode plot for the phase noise transfer function.
