Modelize Warburg element

[Albert_]

Hello,

Is there any way to simulate a Warburg element/impedance in Multisim?

Warburg element is an impedance whose expression is:

Z(jω)=A_W/(jω)^0.5

Where Aw is a constant.

Any idea?

Thanks for your time.

You can use the Laplace component and type in your expression. 

See attached circuit. I've set up in a voltage controlled current source configuration: I=V * H(s).

As such, the expression you enter into the Laplace function should be 1/Z(s). 

This model will work well in AC analysis, but not in Transient. Run AC analysis and you'll see a plot of -I(V1), which is just the current going to this element.

I will try your solution. Thank you very much for your time
