Numeric responses must be either an integer (if exact) or a realnumber with three decimal places, with the least significant numberrounded. Do not use commas. If there are units, the integer partmust be between 1 and 999. Use the following units: Ohm, kOhm, mOhmresistors, etc. Conductances: S, mS, MS, etc. Voltage: V, kV, mV,MV, etc. Current: A, mA, kA, uA, nA, etc. Power: W, mW, kW, uA, pW,etc. Time: s, hrs, ks, ms, etc.
1. Voltage amplifiers are available with Avoc = 8 V / V, Rin =1.8 kΩ, Ro = 850 Ω. With a 12 V DC power source, each amplifierconsumes 1.5 mA average current.
a. How many amplifiers do you need to cascade to get at least a1000 voltage gain with a load resistance of 1.0 kΩ?
b.What is the voltage gain Av obtained? (Respond with a roundedwhole number)
c. For the cascade connection, find the open circuit voltagegain. (Respond with a rounded whole number)
d. If you have a 1.5 mV input, how efficient is the equivalentamplifier?
e. Find the transconductance of the entire circuit.
