For a prototype OpAmp $,$ given VDD$=7$V$,-$VSS$=-7$V$,$ and given gm$2=$gm$6=$gm$7=$ gm$8=5$mS$,$ gm$9=2\mathrm{.}5$mS$.$

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

VGS$1=$VGS$2=$VGS$5=$VGS$6=2\mathrm{.}2$V$,$ VGS$7=$VGS$8=1\mathrm{.}9$V $,$ VSG$10=$VSG$11=2\mathrm{.}1$V$.$

Determine the minimum voltage for the common mode input

At quiesent condition $($v$1=$v$2=$vo$=0),$ VGS$1=$VGS$22$V$,$ Vds$63$V$,$ Vds$36$V$,$ and Vds$4=5$V$.$

For PNP transistor Q$12,$ assume $|$VBE $|0\mathrm{.}7$V$,$ $=100,$ VA$=50$V$.$

Determine the CMRR for theOpAmp in dB if RD$=0\mathrm{.}8$ Kohm, rpi$12=1\mathrm{.}1$ Kohm, ro$8=44$ Kohm, ro$6=26$ Kohm, ro$2=27$ Kohm.

Determine the differential gain for the first stage Adm$1$ in dB if RD$=0\mathrm{.}8$ Kohm, rpi$12=1\mathrm{.}1$ Kohm, ro$8=67$ Kohm.
