QUESTION $10$

${}_{I_k}$

For a prototype OpAmp, given $VDD=7V,-VSS=-7V,$ and given $gm2=gm6=gm7=gm8=5mS,gm9=2\mathrm{.}4mS.$

$VTN=1\mathrm{.}3V,VTP=-1\mathrm{.}0V$

$V_{GS1}=V_{GS2}=V_{GS}=V_{GS}=2\mathrm{.}0V,V_{GS}=V_{GS}=1\mathrm{.}7V,V_{SG10}=V_{SG11}=1\mathrm{.}7V.$

Determine the maximum voltage for the common mode input
