Q#1 MOSFET GATE EE 2025 MCQ +1 mark -0.33 marks

Which one of the following statements is true about the small signal voltage gain of a MOSFET based single stage amplifier?

Common source and common gate amplifiers are both inverting amplifiers

Common source and common gate amplifiers are both non-inverting amplifiers

Common source amplifier is inverting and common gate amplifier is non-inverting amplifier

Common source amplifier is non-inverting and common gate amplifier is inverting amplifier

Explanation:

For common source Amplifier,

        ∴ Inverting Amplifier

For common gate Amplifier,

                 Non-Inverting Amplifier

For common drain Amplifier,

                 ∴ Non-Inverting Amplifier

Hence, Option (c) is correct.
