Question

a) What is the voltage gain, Av= Vo/Vt , for the following amplifier?

b) What is the voltage gain, Av= Vo/Vt , for the following amplifier?

d) If we cascade the amplifiers in the reverse order, what is the voltage gain, Av=Vo/Vt?

e) Now the cascade of amplifiers from part c) is used to amplify the output of a sensor. The
Th?venin equivalent circuit for the sensor is shown. What is the voltage gain,Av=Vo/Vt, from
the sensor to the amplifier output?

f) Now, the sensor output is being amplified by the cascade of amplifiers from part d). Determine
the voltage gain,Av=Vo/Vt, from the sensor to the amplifier output.

g) Provide a clear, concise explanation for the relative values of the gains you calculated in parts c)
through f). Briefly discuss the practical implications of what you?ve found.

Explanation / Answer

a.V0 / Vin = -Rf / Rl( V2 - Vin ) V2 = voltage of + point. V1 = voltage of - point. Rf= 4R. Rl =R. gain= 4 . b. voltage gain= -3/2 c. on cascading, gains multiply. =-6 d. same gain = -6
