Dejitter Circuit Analysis
A-4
The VCO is an integrator and contributes
one pole.
The feedback loop consists of the divide
by 16
Putting everything together, the loop
equation becomes:
Simplifying to the final form of the
closed loop equation.
The characteristic equation for the system
takes the form:
Which is the denominator of the closed
loop equation.
Therefore the natural frequency of the
system is given by:
