Red Tiger Technologies excels in BJT technology for integrated circuits. To outshine them, Blue Tiger’s boss, Xuyang, sends spy Yiyang to infiltrate Red Tiger. Yiyang uncovers three unresolved BJT problems of Red Tiger. Xuyang assigns his engineers the task of solving these critical issues, aiming to secure Blue Tiger’s dominance.

Question 1.  Small Signal Analysis of BJT

Consider the following BJT amplifiers, determine their small-signal, open-circuit voltage gain respectively.  Neglect the Early effect. Hint: Try to follow the steps to solve each question

1) Complete a D.C. Analysis.

2) Calculate the small-signal circuit parameters for each BJT.

3) Carefully replace all BJTs with their small-signal circuit model.

4) Set all D.C. sources to zero.

5) Analyze small-signal circuit.
