Hi!
As shown in the attached circuit, I have to calculate the current I_out of a differential amplifier with current mirror load where the output is fed back with M5 to one input.
Given are the transconductances of all transistors (where g_m1 to g_m4 are all equal), g_DS2 and g_DS4 (I suppose it's the drain to source conductivity) and the voltages V_ref and V_dd.
I have derived the small signal amplification but I doubt this is useful in that case. I suspect that the feedback forces the gate of M2 to V_ref, but I'm not sure.
Any hints are highly appreciated.
