An amplifier is required to amplify the output signal from a transducer that produces a constant current of is = 100 μA at an internal resistance varying from Rs= 10 kΩ to 100 kΩ. The desired output current is io = 20 mA at a load resistance varying from RL = 20 Ω to 500 Ω. The variation in output current should be kept within ± 3%. Determine the design specifications of the amplifier.
