Differential Pair with MOS load

enter image description here

$A_v=-g_{m_{N}}\Big( \frac{1}{g_{m_{P}}} || r_{o_{N}} || r_{o_{p}} \Big)$

$ \hspace{0.6cm}\approx \frac{-g_{m_{N}}}{g_{m_{P}}} $
$ \hspace{0.6cm}\approx -\sqrt{\frac{\mu_n (W/L)_N}{\mu_p (W/L)_P}}$

$A_v=- g_{m_{N}}(r_{o_{P}} || r_{o_{N}})$
