This example shows an audio amplifier circuit based on an N-channel JFET. The desired operating point is taken to be Vds=5V, Id=2mA and Vgs=-2V. The manufacturer datasheet gives the JFET forward transfer conductance and output conductance values as 3mS and 50uS. These values are used to...
The JFET transistor differential amplifier herein serves as an input stage, as for an electrometer operational amplifier, and exhibits high input impedance and low leakage current. This is achieved by biasing the JFET transistors so as to operate in the ohmic region rather than the saturation ...

As an example, let’s say VP = -4V, this means that the drain voltage, vDS, must be greater than or equal to –(-4V) in order for the JFET to remain in the saturation (normal operating) region. This description indicates that the JFET is a depletion-type device. We expect...
