In a small signal differential gain vs input CM level graph, the gain decreases after V2 due to? |
| A. | As the input voltage increases, the output will be clipped |
| B. | When the input voltage to the transistors are high, the transistor enters saturation region and increases the current, which inturn decreases the output voltage = VDD – Rd.Iss |
| C. | When Common Mode voltage is greater than or equal to V2, the input transistors enter triode region, the gain begins to fall |
| D. | Increasing the input voltage beyond V2 causes the gate oxide to conduct and the gain is reduced |
| Answer» D. Increasing the input voltage beyond V2 causes the gate oxide to conduct and the gain is reduced | |
