Let me try if I can help. I would like to check the circuit intuitively.

Below analysis is based on the limited adjustable variables (Vbias2 and Vbias).

If Iref is fit, basically V(X) is fit, this means that you would have only V(X) to distribute for Vsd of MP4 and MP6. " N4 M( W2 `5 S& t o
L1 Q; Q& r- p5 b1 n3 s
V(P1) and V(P2) is determined by Vbias2, increase Vbias2 would decrease V(P) and push MP5 and MP6 closer to the linear region.6 \* E# y6 H" E' M+ g3 p9 K( M

Vbias would determine V(Y), increase Vbias would increase V(Y), and push MN1 deeper into saturation region.
