Alright, makes sense, but how do I fix that? I guess I can put resistors in there to drop voltage to get it down to ((VCC-Vbe)+Vtail)/2 -> ((12-0.7)+1.25)/2 or about 6.3V but the whole point of this arrangement was to get the ridiculously high gain you get by using a current mirror active load instead of resistors. Loads of devices use this arrangement, granted, with a normal current mirror instead of one using Sziklai pairs. How do they avoid this issue?
