FET is a resistor whose resistance value is controlled by the potential applied to the control terminal termed as Gate. The conducting region is called a channel which may be either p type or n type based on the substrate used. The channel conductivity mainly depends on the gate region. I-V characteristics are expressed in a detailed manner with necessary equations. JFET parameters are another crucial factor to understand its characteristics. The small signal model of JFET is illustrated in a very lucid manner. 

Keywords: Structure, Structure, Working principle, I-V Characteristics.
