Phase margin revisited: Phase-robot locus, bode plot, and phase shiftersIn learning undergraduate controls, one of the most and confusing concepts is that of phase margin (PM). One frustration is the difficulty in conceptualizing what physical process could produce the pure phase shift referred ...
Other Parts Discussed in Thread:LP38852 Hi All, Our customer hope to know the phase margin of LP38852 because there is no bode plot. Do you have example bode plot? The performance at typical schematic should be OK. I know that you recommend to set Fz around 12kHz, then ...

TheGain and Phase Margin Plotdoes not define default bounds. TheCheck Gain and Phase Marginsblock defines default bounds and enables these bounds for assertion. You can view the margins in a table or on a Bode, Nichols, or Nyquist plot. ...

The phase margin and gain margin tests The previous analyses tell us what the bandwidth and DC gain of a closed-loop system is, but do not consider the question of whether a system will oscillate or have large amounts of overshoot. By using a simpleBode plottechnique and a method known ...

Together, these two numbers give an estimate of the "safety margin" for closed-loop stability. The smaller the stability margins, the more fragile stability is. You can display the gain and phase margins on a Bode plot as follows. First create the plot: Get bode(G), grid Then, right...
