Voltage amplifiers are available with Avoc = 8 V / V,

Rin = 1.8 kΩ, Ro = 850 Ω. With a 12V DC power source, each amplifier

consumes 1.5 mA average current.

a. How many amps do you need to cascade to get so minus a voltage gain of 1000 with a load resistance of 1.0 kΩ?

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

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

d. If you have a 1.5 mV input, how efficient is the equivalent amplifier? and. Find the transconductance of the entire circuit.
