当然,实际设计电路时要考虑冗余,这部分体现为相位边界和增益边界,分别指: 相位边界(Phase margin):Av、Gv、loop gain为 0dB 时,该频率对应相位与 -180° 的距离; 增益边界(Gain margin):相位延迟为 -180° ,该频率对应增益与 0dB 的距离; 在图5中,相位边界约为 85°,增益边界约为 55 dB,这种都是较为安...

Because you can specify only one linearization input/output pair in this block, the linear system is Single-Input Single-Output (SISO). You can specify one minimum bound each for the gain and phase margin and view them on the selected plot or table. You can also check that the bounds ...
The Bode plot looks good, it has good phase and gain margin are good. 100Hz start is fine. The only concern i have the loop bandwidth. Please use equation to design COUT for the better bandwidth. you can also use webench to help you design the right...

The difference between unity and the value of |βA| at the frequency of -180° shift, called the gain margin, is usually expressed in dB. The difference between the phase angle at the frequency where |βA| =0dB and -180° is termed the phase margin. ...
First create the plot: Get bode(G), grid Then, right-click on the plot and select the Characteristics -> Minimum Stability Margins submenu. Finally, click on the blue dot markers. The resulting plot is shown below: This indicates a gain margin of about 9 dB and a phase margin of ...
