"WebIn practice, the voltage divider bias is less effective with JFET than BJT. This is because in BJT, V BE = 0.7 V (silicon) with only minor variations from one transistor to another transistor. But in a JFET, the V GS can vary several volts from one JFET to another. Current-Source Bias: " - Fixed bias vs voltage divider bias
