Suggestion for Differential amplifier Layout based on different Fingers

[Khan_001]

Hi Everyone,
can some suggest me how to place these transistor (Differential amplifer )in layout--Goal is to utilized min area and use common centriod method
3 nmos each having W/L (24/3)--- using finger concept, become W:6u, L:3u and Finger 4Hi Everyone,
3 Pmos each having W/L (16/3)--- using finger concept, become W:4u, L:3u and Finger 4
Tail Transistor and bias transister: 10/1---- W=5u, l=3 ,Finger 2
