Question #1 (8 pts) Two identical current amplifiers with input resistance 5k , output resistance 50k , and short-circuit current gain 3.3A/A are placed in series in the setup shown below. A voltage source Vs with source resistance 1K is connected to the input. The load resistance R L = 1.5k . Use the constant-voltage drop model (CVDM) for the diodes. (a) [2 pts] Redraw the circuit and replace the amplifiers with their equivalent circuits. ( note: you can leave the diodes as they are). (b) [3 pts] What DC value of V s is required such that the maximum symmetric voltage swing can be achieved at the output, V
