FET as Variable Resistor

Voltage-Controlled Resistance When a JFET operates in the ohmic region, it usually has VGS 5 0 to ensure hard saturation. … More

FET is the preferred device for most switching applications. Why?

Because there are no minority carriers in an FET. As a result, it can switch off faster since no stored … More
