Figure 4.27. An N channel JFET has its source grounded. A battery labeled V sub GG has its positive terminal grounded. The negative terminal goes to one end of a 100 k ohm resistor. The other end goes to the gate of the FET. The drain of the FET connects to one end of a resistor labeled R sub D. The other end of this resistor connects to the positive end of a battery labeled V sub DD. The negative end is grounded. End verbal description.
