Webdivider or voltage follower circuits can be used. Inverting Amplifier (DC Coupled): In this case, the voltage divider biasing method is the best to use, unless you happen to have a voltage follower bias already in your circuit, in which case you can merely connect to that. Since the voltage divider is only connected to the input pin of the op- 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:
