Transistor Collector Feedback Bias
In Figure, the base resistor RB is connected to the collector rather than to VCC, as it was in the base bias arrangement discussed earlier. The collector voltage provides the bias for…
Transistor Emitter Feedback Bias
If an emitter resistor is added to the base-bias circuit, the result is emitter-feedback bias, as shown in Figure. The idea is to help make base bias more predictable with…
Transistor Base Bias
This method of biasing is common in switching circuits. Figure shows a base-biased transistor. The analysis of this circuit for the linear region shows that it is directly dependent on βDC.…
Transistor Emitter Bias
Emitter bias provides excellent bias stability in spite of changes in β or temperature. It uses both a positive and a negative supply voltage. To obtain a reasonable estimate of the…
Transistor Voltage Divider Bias
AÂ method of biasing a transistor for linear operation using a single-source resistive voltage divider. This is the most widely used biasing method. Up to this point a separate dc…
Testing a Transistor with a Digital Multimeter
Several faults that can occur in the circuit and the accompanying symptoms are illustrated in Below Figure. Symptoms are shown in terms of measured voltages that are incorrect. If a…
Troubleshooting a Biased Transistor
Several faults can occur in a simple transistor bias circuit. Possible faults are open bias resistors, open or resistive connections, shorted connections, and opens or shorts internal to the transistor itself.…

Current and Voltage Principle Animation
The animation above shows miniature trucks carrying bags of energy from the battery to a light globe. The light globe takes the bags of energy and uses this energy to…
Batteries in Series and Parallel Animation
What happens when we connect the batteries in series and parallel? When we connect the Batteries in Series, we will get sum of voltages of both the Batteries. Here we…
