It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier configurations. This doesn’t come up as often as it used to, but it is still a good ...

Just as the common emitter amplifier and common base amplifier each tied those respective transistor terminals to a fixed potential and used the other two terminals as amplifier input and output, so ...

Emitter/source degeneration is a technique used to guard against drift in transistor parameters like beta. In addition, it helps linearize the small signal output. The transfer characteristic of a BJT ...

The circuit in Figure 1 sinks a constant current (ICE3) through Q3’s collector and emitter. This design is balanced so changes in Q3’s base-emitter voltage (VBE) don’t affect the current sink’s ...

In the undergraduate active-circuits course in electronics engineering, the analysis of circuits is simplified, as it must be for introductory presentation. One of the simplifications that is often ...
