To find the various parameters of the NMOS differential amplifier and the corresponding differential output voltage;

Step 1: Calculate   (quiescent drain current):    is given by   , which is 0.2 mA.

Step 2: Calculate g_m (transconductance):
g_m is given by the equation   , where    is the transconductance parameter.

Given   and W/L = 32, we can calculate    as:
   = 1.13 mA/V.

Step 3: Calculate r_out (output resistance):
   is given by   , where   is the channel-length modulation parameter.

Given V_A = 10 V, we can calculate r_out as:
r_out = 1 / (10 V * 0.2 mA) = 100 k?.
