WebMar 15, 2024 · The voltage gain for the common base amplifier is the ratio of V OUT /V IN, that is the collector voltage VC to the emitter voltage VE. In other words, VOUT = VC and VIN = VE. as the output voltage VOUT is developed across the collector resistance, RC, the output voltage must therefore be a function of IC as from Ohms Law, VRC = IC*RC. WebDec 26, 2024 · Thus, the base voltage must be less than the collector, but greater than the emitter. That also means the collector must be greater than the emitter. In reality, we need a non-zero forward voltage drop (abbreviated either V th, V?, or V d) from base to emitter (V End up being) to “turn on” the transistor. Usually this voltage is usually ... WebThus, for example, in some embodiments, the collector 232 could include a first collector region 232.1, which is an N− silicon collector region within the first trench 218 a, and a second collector region 132.2, which is an N+ silicon collector region above the first trench 218 a, and the emitter 233 can include first and second emitter ... other words for what i mean by this

"WebThe narrowing of the collector does not have a significant effect as the collector is much longer than the base. The emitter–base junction is unchanged because the emitter–base voltage is the same. Base-narrowing has two consequences that affect the current: There is a lesser chance for recombination within the "smaller" base region. " - The collector emitter voltage is usually
