differential pair output offset

offset of differential pair

Hi,
I am trying to simulate a simple differential pair amplifier but I see offset on my output how can I minimize this offset?
thanks,
M

A symmetrical differential pair hasn't an offset. For complex parts, e.g. OP library models, sometimes an artificial offset is assumed by the simulator, but rather unlikely for a simple differential pair. So you apparently have an unsymmetry in your circuit. Remove it to get zero offset.
