Can I use half analysis method If I can why It has current m

Can I use half analysis method?

If I can, why??? It has current mirror circuit, So. It is not symmetric. is it?

Solution

We can\'t use half analysis method as the circuit we are dealing with is not current mirror circuit as it is not symmetric. For the first two layers of mosfet, the mosfet in the left has gate and drain shorted unlike mosfets in the right.
