Problem 4. (10 pts) Voltage amplifiers are available with Avoc = 8 V / V, Rin = 1.8 kΩ, Ro = 850Ω. With a 12V DC power source, each amplifier consumes 1.5 mA average current.

a.how many amplifiers does it need to connect a cascade to obtain at least gain a voltage of 1000 with a load resistance of 1.0kΩ?

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

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

d. If you have a 1.5 mV input, What is the efficiency of the equivalent amplifier?

e. Find the transconductance of the entire circuit.
