Ideal Diode using SDD in ADS

[Jabu]

Hey there!

I want to model an ideal diode in ADS using a SDD component! Zero current below threshold voltage Vth and zero resistence above. Can't be too difficult but I simply cannot figure it out (which is rediculous). Anyway, this is what I tried for the equ: " I[1,0] =if (_v1<0.7) then (0) else (_v1/1E-10) endif " but it does not converge with HB and the 1e-10 is not really satisfying. Can someone help?

Increase tones and oversampling factor.

Zero current below threshold voltage Vth and zero resistence above.

When you think about it, a diode at zero ohms must also have zero volts. It is incompatible with a voltage differential.

If you want 0.7V differential, then the diode automatically adjusts its internal resistance so it that admits the available Amperes.
Thus to display 0.7V drop, it becomes:

* 700k ohms when passing 1uA.
* 700 ohms when passing 1mA.
* .7 ohm when passing 1A.
etc.
