Calculate ib and ie for 0 ltvbbltvbbmax vbbmax can be

Question

Analyze the following circuit using PSpice. It is suggested that the transistor model of "QbreakN-X NPN" be used. You may have to edit some parameters of the model, such as β and V_BE (on).

Let V_BE(on)= 0.7 V and β = 1 xy (xy are the last two digits of your student ID, so the value of β is in the range of 100-199).

Calculate I_B and I_E for 0 BBBB(max). V_BB(max) can be arbitrarily set but the transistor must be in the saturation mode at V_BB(max).

You are required to turn in a brief report (no more than 4 pages) which includes:

1. PSpice model file

2. The schematic of the circuit you build for your simulation

3. Three plots:

• I_B vs. V_BB
• I_c VS. V_BB
• The ratio of I_c/I_B vs. V_BB

4. Find the value of V_BB at the transition between the forward active mode and saturation mode.
