Trying to find a fast way to draw impedance Bold plot of passive networks

[qilongliu]

Hi guys, my questions is. is there any way to draw an impedance Bode plot quickly and precisely? The precision is viewed good enough when their Asymptotes are achieved. I want to use this method in analog circuit design, so only passive components- resistance and capacitance -are considered.

Give an example of how you do it now, and we may be able to help you find a better way do to it.
