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…
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…
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…
Bias Stability Factor of Transistor: Bias Stability Factor of Transistor - Only the fixing of a suitable operating point is not sufficient but it is also to be ensured that…
Selection of Operating Point in Transistor Biasing: To study the selection of operating point in Transistor biasing conditions on the performance of a transistor, it is necessary to draw a…
Tuned Base Oscillator - Definition and Working Principle: When a parallel tuned L-C circuit is placed in the base-to-ground circuit, the oscillator is known as the tuned base oscillator. The…
Tuned Collector Oscillator - Definition, Working and Equation: The basic circuit of a tuned collector oscillator is shown in Fig. 21.7. It is called the tuned collector oscillator, because the…
Light Emitting Materials: Since the eye is only sensitive to light of energy hf ≥ 1.8 eV (~ 0.7 μm), semiconductors of interest must have energy band gaps larger than this…
