2: For the cascaded amplifier below, find:
a) The individual voltage gain expressions for V1, V2 and V3.
b) The overall output voltage of the amplifier.
c) Assuming all of the stages are powered by a 5V supply, will the any of the stages be
saturated? If so, which ones and what is the actual output voltage?

Let, V1=200mV, V2=100mV, V3=50mV
R1=5k, R2= 2.5k, R3= 1.25k, R4= 25k, R5=3k, R6= 30k
