JFET Temperature Effects: The JFET, like other solid state devices, is subject to the JFET Temperature Effects. However, it is possible to bias the JFET such that it will exhibit a zero temperature coefficient i.e.…
FET Configurations: FETs (JFETs and MOSFETs) have three configurations just as BJTs have. The three FET Configurations—the common gate, common source, and common drain configuration have been given in Fig. 13.11. Input and output terminals…
Advantages and Disadvantages of JFET: Junction field-effect transistors combine several merits of both conventional (or bipolar) transistors and vacuum tubes. Some of these advantages and disadvantages of JFET are enumerated below : 1. Its operation…
Junction Field Effect Transistor (JFET) - Construction, Symbols and Operation: Depending upon the majority charge carriers, Junction Field Effect Transistor (JFET) have been classified into two types, namely (i) N-channel JFETs with electrons as the…
Thermal Resistance - Definition, Circuit Diagram and Equation: With power transistors, a designer often uses a heat sink to get a high power rating for the transistor. As already mentioned, the heat sink allows the…
Various Bias Compensation Methods: During the discussion made for various biasing methods for providing stability to the operating point we have seen that self bias (or potential divider bias) and collector-to-base bias circuits provide better…
Two Supply Emitter Bias Circuit: From the stability point of view, this two supply emitter bias circuit is the best of all already discussed circuits, but it has one drawback that it requires two power…
Base Bias Circuit With Collector and Emitter Feedback: In this Base Bias Circuit With Collector and Emitter Feedback circuit, as obvious from its name, both collector and emitter feedbacks are used in an attempt to…
Base Bias with Collector Feedback Circuit: This Base Bias with Collector Feedback Circuit is like a fixed bias circuit except that the base resistor RB is returned to the collector terminal instead of supply VCC.…
Self Bias or Potential Divider Bias Circuit: This is the most commonly used biasing arrangement. The arrangement of Self Bias or Potential Divider Bias Circuit is shown in Fig. 12.17 (a). The name voltage divider…
