AN105 FETS AS VOLTAGE-CONTROLLED RESISTORS

www.DataSheet4U.com AN105 FETs As VoltageĆControlled Resistors Introduction: The Nature of VCRs A voltage-controlled resistor (VCR) may be defined as a three-terminal variable resistor where the resistance value between two of the terminals is controlled by a voltage potential applied to the third. For a junction field-effect transistor (JFET) under certain operating conditions, the resistance of the drain-source channel is a function of the gate-source voltage alone and the JFET will behave a.
