Question: two amplifiers are to cascaded between a signal source and...

Question details

Two amplifiers are to cascaded between a signal source and load, as shown below Signal Source Amplifier1 Amplifier 2 Load Rout2 in2 in 1 Rinl Rm1in1 Rin2 SIG İsig (10pA) sin (27/t) Rout 1 10ks Rout 2 -100Ω RL 100, (A) Accounting for all coupling effects, give an expression for the circuits overall trasresistance gain, Rtot - Vout/isig. Calculate the value for this gain. (B) Calculate the amplitudes of i1, Vn2 and vout. (C) If the amplifiers input and output resistances could be modified, describe the changes that would be required to maximize the total transresistance gain. State the value of the maximum gain that can be achieved under these modifications
