Title: Current dependent voltage source in Spectre
Post by fernando.g.r on Dec 6^th, 2010, 2:50am

Hello,

I'm trying to specify a current dependent voltage source in Spectre, which also depends on a voltage node.

The expresion i'm trying to model is :

Code:

V(Emem) = -I(Roff)*V(N1)*(R_OFF-R_ON)

So i tried with no result:

Code:

Emem Plus N2 dc=-I(Roff)*V(N1)*(R_OFF-R_ON)

Can you help me? Thanks

You could either try to use the pccvs component (together with a vccs for the control voltage) or write a simple Verilog-A model.

Thanks!

I finally include a bsource component, and it seems it works.

Thanks for all.
