From the analysis of the proposed PED-controlled PLL model and PLL with second-and third-order LF, we can conclude that the settling time of PID-controlled PLL is too much faster (0.062 ps) than that of the PLL with LF (0.103 ns for second-order LF and 0.109 ns for third-order LF). Bode responses for PM of the model show that the PM values for both the cases of PLL with LF and PID-controlled PLL are well within the limit of stability. Also, it is observed that the PID-controlled PLL system is highly stable. So, the model may be applied as a trade-off for research and industrial applications for acquiring better settling time in communication system.
