You are given two amplifiers, A and B, to connect in cascade between a 10-mV, 100-kΩ source (S) and a 100-Ω load (L). The amplifiers have voltage gain, input resistance, and output resistance as follows: for A, 100 V/V, 10 kΩ, 10 kΩ, respectively; for B, 1 V/V, 100 kΩ, 100 Ω, respectively. Your problem is to decide how the amplifiers should be connected so that the voltage gain is maximum.
(a) SABL
(b) SBAL
(c) Both have the same voltage gain
(d) None as neither combination is able to amplify the input signal
I got this question in exam.
My question comes from Circuit Models for Amplifier in division Signals and Amplifiers of Electronic Devices & Circuits
