Question: You are given two amplifiers, A and B, to connect in cascade between a 10-mV, 100-k? source (S) and a 100-? load (L). The amplifiers have voltage gain, input resistance, and output resistance as follows: for A, 100 V/V, 10 k?, 10 k?, respectively; for B, 1 V/V, 100 k?, 100 ?, respectively. Your problem is to decide how the amplifiers should be connected so that the voltage gain is maximum.
Options
A : SABL
B : SBAL
C : Both have the same voltage gain
D : None as neither combination is able to amplify the input signal
