Question

Please verify the procedure used to calculate the efficiency (n) and the power gain (Av). Is it correct? If not, what would be the correct way to solve it?
For the amplifier shoun in Figure 15determine os. In Ves and gm) -the expression for volt the efficiency of the amplifier "the power gain of the amplifier (AC, Assume the amplifier is working in the midband frequency range. Row 100 Rea 100 kn Rs 8000 Real 2 MOSFET 1.5 V Derive the results, AC Analysis Pat RGI Zine Rc2 Figure 15 Zout Rs TRIM S. A. mv is in 2v

Explanation / Answer

YES IT IS CORRECT. HE DID ANALYSIS FOR ASSUMING MOSFET IN SATURATION.

FOR FINDING gm HE DID DIFFERENCIATION WITH RESPECT TO VGS. THE GAIN WILL BE gmR PARALLEL WITH RL.
