Attached is a simulation of a differential amp with two identical inputs. The output voltage is around 8 volts, with a 5 mA input which would make the gain about 1600. The formula for the gain is RC * gm. Rc is 75k whilst gm is Ic/25mV approx 200uA/25mV. This does not work out at 1600.
Can someone tell me what's wrong here please?
