Figure (a) shows the fixed bias circuit
Figure (a) Fixed bias circuit.
For DC analysis, the coupling capacitors are open circuit and the current through RG is zero.Hence, RG can be replaced by short-circuit equivalent and the fixed bias circuit is shown in Figure (b).
Figure (b) Sinnplified fixed bias circuit.
VGS is fixed in magnitude because VGG is a fixed DC supply. Hence, the name fixed bias circuit.
The drain current for fixed bias can be calculated from equation,
Applying KVL to the output circuit,
