Phase Locked Loop Circuits - UC Santa Barbara
web.ece.ucsb.eduvaries with the loop transfer function and input. A frequency domain approach will be used, specifically describing transfer functions in the s-domain. Ve(s)/∆φ = KD φout(s)/Vcont(s) = KO /s Note that the VCO performs an integration of the control voltage and thus provides a factor of 1/s in the loop transfer function.
