Bjt common collector
WebApr 17, 2024 · Thus, for the positive swing, the voltage at the base will be: V B D C + V I N ≈ 7 V + 4 V ≈ 11 V at the peak of the input signal amplitude. And this means the transistor will enter the saturation region because of V B > V C + 0.5 V. And in saturation, the base-collector is in forward conduction. WebAug 16, 2024 · Symbol of BJT.
