Voltage amplifiers are available with Avoc = 8 V / V, Rin = 1.8 kΩ, Ro = 850 Ω. With a 12 V DC power source, each amplifier consumes 1.5 mA average current.

a. How many amplifiers do you need to connect in cascade to get at least a 1000 voltage gain with a load resistance of 1.0 kΩ?

b. What is the voltage gain Av obtained? (Respond with a rounded whole number)

c. For the cascade connection, find the open circuit voltage gain. (Respond with a rounded whole number)

d. If you have a 1.5 mV input, how efficient is the equivalent amplifier?

e.Find the transconductance of the entire circuit.
