Question

Problem 2: Figure 2 shows a multistage BJT amplifier, assume that all BJTs have the following parameters values ? = 100, VBE = 0.7 V, VA = ? • State the amplifier configurations used and their characteristics • Draw the small signal model of the amplifier and derive expression for the overall voltage gain Vout/Vin • Using your ID: XX-ABCD, Set the gain to the value of “0.AB” by changing the value of ANY of the used resistors. Calculate the input and output resistances of the multi-stage amplifier (input resistance of first stage and output resistance of the second stage) based on your new design values. RG 5.1 k?
