Some articles on phase margin, phase, margin:
... Next, the choice of pole ratio τ1/τ2 is related to the phase margin of the feedback amplifier ... for every factor of ten increase in frequency, the gain drops by the same factor The phase margin is the departure of the phase at f0 dB from −180° ... Thus, the margin is Because f0 dB / f1 = βA0 >> 1, the term in f1 is 90° ...
... Frequency f0dB is needed later to find the phase margin.) Figure 7 shows the corresponding phase comparison the phase of the feedback amplifier is nearly ... In this vicinity, the phase of the feedback amplifier plunges abruptly downward to become almost the same as the phase of the open-loop amplifier ... Figure 7, it is seen that the unity gain frequency f0dB and the phase-flip frequency f180 are very nearly equal in this amplifier, f180 ≈ f0dB ≈ 3.332 kHz, which means the gain margin and phase margin are ...
Famous quotes containing the words margin and/or phase:
“Everything that explains the world has in fact explained a world that does not exist, a world in which men are at the center of the human enterprise and women are at the margin helping them. Such a world does not existnever has.”
—Gerda Lerner (b. 1920)
“The Indians feel that each stage is crucial and that the child should be allowed to dwell in each for the appropriate period of time so that every aspect of his being can evolve, just as a plant evolves in the proper time and sequence of the seasons. Otherwise, the child never has a chance to master himself in any one phase of his life.”
—Alan Quetone (20th century)
