Differential inputs

Could you please supply a couple of pointers on a method to model a
differential input buffer containing both self biasing and differential
termination. In an application the inputs to the buffer are AC
coupled. The buffer will then swing about its bias value. In
addition, the +/- signals are internally terminated with approximately 100
ohms.

The bias point could vary with temp and voltage so I would prefer to derive
the values from the spice model. The 100 ohms is also a rough number and
I would somehow prefer to capture the characteristics from the spice models.

Thanks
