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 VBE (on).
Let VBE(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 IB and IE for 0 BBBB(max). VBB(max) can be arbitrarily set but the transistor must be in the saturation mode at VBB(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:
- IB vs. VBB
- Ic VS. VBB
- The ratio of Ic/IB vs. VBB
4. Find the value of VBB at the transition between the forward active mode and saturation mode.
