Difference between JFET and MOSFET: The Difference between JFET and MOSFET are quite similar in their operating principles and in their electrical characteristics. However, they differ in some aspects, as…
Enhancement Type MOSFET - Construction, Operation and Characteristics: Although DE-MOSFET is useful in special applications, it does not enjoy widespread use. However, it played an important role in history because…
Depletion Type MOSFET - Construction, Operation and Characteristics: As we know already that when the gate is biased negative w.r.t. the source in an N-channel JFET, the depletion-region widths are…
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…
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,…
Crystal Oscillators - Circuit, Working, Advantages and Disadvantages: In crystal oscillators, the usual electrical resonant circuit is replaced by a mechanically vibrating crystal. The crystal (usually quartz) has a high…
