Recall that Matlab provides a feedback function for evaluating transfer functions: Aprime=feedback(A,C). The source-degeneration resistor serves double duty by sensing the output current for the ...

Once the open-loop transfer function is modeled, it’s necessary to design the frequency compensator such that it achieves the best performance possible. Because the frequency response of the above ...

For most closed-loop feedback control systems, there are two basic rules: Phase margin is greater than 45° (less than 315°) when the loop gain is greater than 0dB. Gain margin is -20dB or lower ...
