I have attached the question in the picture below. I want to understand the problem for my final exam. Please solve all the question below.

1.
In the multistage amplifier circuit below, Vcc=VEE=5 V. The three ideal current
sources, I1, 12 and I3 bias the amplifier circuits. You can assume that |VBE|= 0.7 V.
The values for I1, 12, 13, B, VA, and Ri are specified in the table below according to

. Identify the ampliﬁer stages . Calculate the dc bias points of all the BJTs (Ic, VCE). Use the bias analysis
results and Vc1=ch to select values for RC] and RC2. . Calculate the differential gain of the multistage ampliﬁer. . Use LTspice to simulate the multistage ampliﬁer circuit. Apply a negative dc
voltage at the input to zero out the output dc voltage.
i. Show results of the dc operating point analysis. Do the simulation
ii. Run a transient analysis at a frequency of 10 kHz and determine the
overall gain. Do the simulation results agree with your calculations?
iii. Determine the input signal range from the simulation. . Show how would you implement the circuits for the current sources In, 12 and 13
