JFET Transistor: Operation and Characteristics

Junction Field Effect Transistor image

JFET is the first form of field effect transistor to be developed can be used as a voltage controlled resistance or as an electronically controlled switch. In our previous articles, we explain in detail about Field Effect Transistor operation and comparison between Jfet & Mosfet. In this, we are going to explain you in detail about Jfet operation and biasing. Junction Field Effect Transistor: JFET consist of the channel of semiconducting material through which a current flows. Jfet’s are of two types; one is n-channel JFET and another is p-channel JFET. Generally, n-channel JFET are more preferred than p-channel JFET because Read More …

Comparison Between JFET and MOSFET

Comparison between JFET and MOSFET image

Fet is categorized into Jfet and Mosfet, both are quite similar in their operating principles and electrical properties. In our previous articles, we explain Fet transistors and its operation, pn junction diode characteristics in detail. Here we are going to explain you in detail about JFET , Mosfet and difference between them. JFET( Junction Field Effect Transistor): JFET is a voltage controlled semiconductor device used as amplifiers, electronically controlled switches and voltage controlled resistors in many applications. Junction field effect transistor has no p-n junctions but has a high resistivity semiconductor material forming a channel of either n-type or p-type silicon Read More …
