Question

Amplifier configuration shown in the below Figure is with MOSFETS M1, M2 connected respectively in a configuration given by 

• A. Common Source and Common Drain
• B. Common Gate and Common Drain
• C. Common Source and Common Gate
• D. Common Gate and Common Source

Hint:

Remember the basic MOSFET configurations: Common Source (CS), Common Gate (CG), and Common Drain (CD). Pay close attention to where the input and output terminals are.

Answer 1

The Correct Option is D

In the given configuration, the MOSFET M1 is connected in a Common Gate (CG) configuration where the input is applied at the source and output taken from the drain. The MOSFET M2 is connected in a Common Source (CS) configuration, where the input is applied at the gate and output taken from drain. Thus, the correct answer is Common Gate and Common Source.
