Semiconductor Devices: JFET Voltage Controlled Resistor

A voltage controlled resistor is a device whose resistance depends on a control voltage. In this video, we discuss how this can be achieved with a simple JFET using small drain-source potentials. This is known as the ohmic region. References: Semiconductor Devices: Theory and Application/2E; Chapter 11, Section 7.
