For many years I have been working on unraveling the basic ideas behind famous circuit solutions. Thus I gradually managed to accumulate a collection of circuit principles and clever tricks. I have...
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 o...
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 "...
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 t...
