Question 1 (9 points) Consider a CURRENT AMPLIFIER defined by the current transfer characteristic below. This amplifier has R in = 5 k and R out = 90 k . a) [2 pts] What DC input current I in would make possible the largest sinusoidal output signal without any clipping distortion? b) [3 pts] This amplifier is connected to a current source of 2 mA with resistance R S = 5 k . A load of R L = 10k is connected at the output. Assuming this amplifier is operated in the linear region, draw a circuit diagram representing this situation using the model of a current amplifier. c) [3 pts] Assume that the current amplifier receives an input voltage V in instead of an input current (you can imagine an ideal voltage source with no internal
