Gain derivation of pmos amplifier

I believe that output nodes are 5 and 6.

If You draw a small signall circuit You will see a symetry and whole small-signal circuit will reduce to current sources \[g_{m1} V_{in}\], \[-g_{m6} V_{in}\] and resistor \[1/g_{m3}\]. Then your gain should be equal to \[K_V=\frac{g_{m6}-g_{m1}}{g_{m3}}\]

Of course If I didn't made any mistake ;-)
