Figure 4.28. This figure has two parts. In part eh an N channel JFET has its source connected to the positive end of a battery labeled V sub GG. The negative end is grounded. The gate goes to ground through a 100 k ohm resistor. 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. In part b an N channel JFET has its source connected to one end of a resistor, the other end of the resistor goes to ground. There is a capacitor in parallel with the resistor. The top end of the resistor has a plus sign near it and the bottom, ground, end has a minus sign. Between the two signs is a label reading V sub GG. The negative end is grounded. The gate goes to ground through a 100 k ohm resistor. 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.
