How to use the idela_balun in cadence

Hi,

I want to use balun to get a differential input, but when I add it into the schmetic, there is always the netlist error from the component ideal-balun. The simulation cannot continue.

Does anybody know how to set up the ideal-balun in cadence?

Thanks!

Why don't you use a ideal transformer by using 2 very high valued inductors with mutual inductor k=1 between them ?
As a result, you can connect a pin to the ground and it becomes your Balanced input, and the other pins will be UNbalanced output..
