Question | — |
Is it possible for one transistor to switch between two loads? The output collector-emitter part of a transistor can be thought of as a 2-terminal SPST switch controlled by the input base-emitter voltage or base current. So this transistor switch can control only a single collector load. Is it possible to make the transistor act as a 3-terminal SPDT switch? I... (more) |

@coquelicot, I read with interest what you wrote. Definitely it is very enthusiastic and brave... Keep going boldly in this direction! Now I want to ask you, "Do you want to know what the simple truth about bootstrapping is?" To do this, you only need to forget about the existence of the "ground" ... (more) |

A: Purpose of emitter resistor in a common collector amplifier In addition to the previous considerations, I will add a few more. Stages with voltage output (such as a voltage follower) are implemented as voltage dividers consisting of two elements in series "stretched" between supply rails. One of them is "pulling up" and the other is "pulling down" the comm... (more) |

A: Emitter Bypass Capacitor in a CE Amplifier With the capacitor C3 disconnected, the stage has a minimum gain and with C3 connected it has a maximum gain. There is a compromise solution with a moderate gain - to connect a resistor in series to C3. (more) |
