2300_Find the minimum output voltage.jpg

1. Find A1 ( = Vx/Vdiff). You need the transconductance of QN2 and the output resistances of QP2 arid QN2.

2. Find A2 (= Vo/Vx). You need the transconductance of QP3 and the output resistances Qp3 and QN3.

3. Determine the open-loop gain AVOL in VAI and in dB.

4. Use the Miller effectto estimate the break (-3dB) frequency of the open-loop gain. You will need the voltage gain Aar the value of capacitor Cc, and the output resistances of QP2 and QN2.

5. Determine the estimated gain-bandwidth product.

6. Find the maximum output voltage Vomax. This is the value at which OH enters its triode region of operation.

7. Find the minimum output voltage Vomin. This is the value at which ON5 enters its triode region of operation.

8. Determine the minimum common-mode input voltage VCM min. This is the common-mode input voltage at which QN4 enters triode operation.

9. Determine the maximum common-mode input voltage VCM max. This is the common-mode input voltage at which QN1 or QN2 enters triode operation.
