Extraction of bipolar SPICE Gummel-Poon parameters related to reverse Gummel (Ie and Ib vs. Vbc) 
1. Why is the Transport Saturation Current (`IS`) found using the reverse Gummel plot identical to the one found using the forward Gummel plot?
2. How does the magnitude of the Base-Collector Leakage Saturation Current (`ISC`) typically compare to the Base-Emitter Leakage Saturation Current (`ISE`) in a standard BJT?
3. The ideal component of the reverse base current is modeled as the ideal reverse transport current (from the emitter) divided by what SPICE parameter?
4. An extracted value for the Base-Collector Leakage Emission Coefficient (`NC`) of approximately two suggests that the low-current base current is dominated by what?
5. What is the primary reason for performing a reverse Gummel measurement to extract parameters like `BR`, `ISC`, `NC`, and `IKR`?
6. How does the magnitude of the Reverse High-Injection Knee Current (`IKR`) typically compare to the Forward High-Injection Knee Current (`IKF`)?
7. If a BJT were perfectly symmetrical (i.e., the emitter and collector were identical), what would be the expected value of the reverse beta, `BR`?
8. What physical characteristic of a modern BJT is the primary reason that the Reverse Beta (`BR`) is much smaller than the Forward Beta (`BF`)?
9. On the reverse Gummel plot, what does a low value of Reverse Beta (`BR`) look like graphically?
10. In the high-current region of a reverse Gummel plot, the voltage drop across which parasitic resistor becomes dominant and causes the emitter current to roll off?
