WebThe phase margin for this system is approximately 95 degrees. The relation, damping ratio = PM/100, only holds for PM < 60. Since the system is first-order, there should be no overshoot. The last major point of interest is steady-state error. The steady-state error can be read directly off the Bode plot as well. WebFor optimal phase margin of the loop, the ratio of C1/C2 remains 100. Decreasing the ratio will allow for smaller phase margin and possibly faster settling time of the PLL. This is less of a concern for applications operating at constant frequencies versus frequency hopping, however, changes to the recommended external loop filter are not ... dialing southern ireland from uk https://mpelectric.org
