QUESTION $9$

For a prototype OpAmp, given VDD$=8$V$,-$VSS$=-8$V$,$ and given $gm2=gm6=gm7=gm8=5mS,gm9=1\mathrm{.}5ms.$

$VTN=1\mathrm{.}0V,VTP=-1\mathrm{.}0V$

$V_{GS1}=V_{GS2}=V_{GS5}=V_{GS}=1\mathrm{.}8V,V_{GS}=V_{GS}=1\mathrm{.}6V,V_{SG}10=VSG11=2\mathrm{.}3V$

Determine the maximum voltage for the common mode input
