How can I configure the parameters of the CCCS and CCVS? If I have in my circuit a current called "I" and a CCCS of 0.5I and a CCVS of 12I values.

Does this help?

An example of how to use the CCCS and CCVS elements.

What is the syntax for CCVS parameters ?

@m237b,

Please do not double post.

Very new user here. I still don't understand how they work. I have a branch of my circuit with current Ix. another branch has a CCCS of 4Ix. I understand how the R2.nA thing works, but how to I do four times that?

@dcalcoda,

Welcome to CL.

Please make your circuit unlisted or public so that people can see what you are enquiring about.

In general for the VCVS, VCCS, CCVS and CCCS, to scale the transfer ratio (Vout/Vin, Vout/Iin etc.), double click on the element or do:

Right-click > Edit Parameters

and edit the k parameter.

You can also use the Voltage and Current Sources as arbitrary behavioural sources:
