Question

8. Consider the circuit of problem 7. Assuming the transistor is in its active region, draw the appropriate linear circuit used to analyze the time-dependent ("a.c.") behavior including the appropriate transistor model. You can assume the signals are high enough in frequency that the capacitors act as shorts to the signal. You do not need to solve this circuit.

Please include all steps and a clear drawing. Thank you

Answer 1

As diagram of question 7 is not given so a general circuit of BJI in active mode is presented let A BJT Great as shown in figure in this circuit If capacitors cu cct c_cs are Junction capacitor are active if we consider high frequency operate and ignore capacitor final circuit for circuit given in figure (1) with be as follows \r\n equivalent cruet of BJT for Linear Analysis step to draw e great/lets understand by example step 1 Remove all capacitor connected in circuit step 2 draw theorem eq at input side step 3 Determine all operands points Like output r mitten \r\n write small signal equation for all operating point connect only model and short circuit all capacitor (Taking high frequency) rightarrow connect al External restive element internal
