QUESTION 2: A class-A emitter follower biased with a constant current source is shown below. Assume circuit parameters of V ¹ = 14 V, V = -14 V, and R₂ = 78 n. The transistor parameters are ß = 69 and VBE(On) = 0.69 V. The minimum current in Q₁ is to be ig₁(min) = 0.044 A and the minimum collector- emitter voltage is to be VCE(min) = 0.64 V. Determine the value of R that will produce the maximum possible output voltage swing. What is the value of Io? What are the maximum and minimum values of iE1? Then calculate n, the power conversion efficiency.

2. The transistor parameters are ß = 69 and VBE(On) = 0.69 V. The minimum current in Q₁ is to be i₁(min) = 0.044 A and the minimum collector- emitter voltage
is to be VCE(min) = 0.64 V.
Determine the value of R that will produce the maximum possible output voltage swing. What is the value of Io? What are the maximum and minimum values of
iE1? Then calculate n, the power conversion efficiency.
