WebJan 27, 2024 · If I have an NPN transistor and let's say we set the base voltage higher than the collector voltage.(Emitter is connected to GND).There are 2 currents flowing in the base because we have two forward biased junctions inside the diode , 1 is the current flowing from emitter to base and 1 is the current flowing from collector to base. WebFor details, see Appendix A: Homojunction BJT Physics. Therefore, the most important difference between the gain mechanism of the standard BJT and the floating base photo-BJT is the exponential dependence on a photo-voltage . instead of an electrical voltage.
