current-controlled current source in Spectre

current controlled current source

Dear everybody,

I am wondering how I can use "cccs" from analoglib in Cadence to build an ideal differential current amplifier. The cccs is two-port instance, no like vccs and vcvs, which are 4-port instances.

Which properties should I specify besides the " current gain"?

Many thanks.

The controling part is the current flowing throught a voltage source. You need to specify the name of the voltage source in "the first column of the value" and be careful about the current direction.
