This dc (bias) circuit becomes an amplifier now simply by adding a signal source at the gate as in Fig. 5.2. This requires a coupling capacitor, as shown here in the complete circuit, to prevent disturbing the bias upon connecting the input signal to the circuit.

In the amplifier of Project 5, the signal will be superimposed on the bias voltage at the node of VGG. This can be facilitated with LabVIEW and the DAQ. A capacitor, as in an actual amplifier, is ...
