Hi everyone!
I am trying to layout a common centroid diff pair as below:
GND D1 S D2 S D1 S D2 S D1 GND D2 S D1 S D2 S D1 S D2 GND
GND D2 S D1 S D2 S D1 S D2 GND D1 S D2 S D1 S D2 S D1 GND

but i need help connecting the gates and source and drains such that the layout becomes symmetric!
can any one please post me a figure of your own layout of diff amp?

thanks a lot!
