Overview of JFET Technology
Junction Field Effect Transistors (JFETs) are a type of field-effect transistor that utilize an electric field to control the flow of current. They are characterized by their three terminals: source (S), drain (D), and gate (G). The gate terminal is reverse-biased, creating a depletion region that modulates the current flowing from the source to the drain. This unique operation allows JFETs to excel in various applications, particularly in analog electronics.
