Semiconductor Devices: JFET Analog Switch

Analog switches can be used in place of mechanical switches for turning on and off small analog signals. The advantages include no moving parts for extended lifespan, "clickless" switching, and remote or programmable switching. In this video we discuss the basic operation of a JFET analog switch along with a more complex variation which exhibits improved performance.
