Study Notes
P-Channel JFET Construction and Operation
- The construction of a p-channel JFET is similar to that of an n-channel JFET, with the only difference being the reversal of p-type and n-type materials.
- The operation of a p-channel JFET is shown in Fig. 9.46 and Fig. 9.47.
- The action of drain current is reversed compared to an n-channel JFET, with current flowing due to the majority of negative Vgs voltage.
- In a p-channel JFET, holes are the majority carriers, opposite to those in an n-channel JFET.
- The drain current increases when the Vgs voltage becomes more negative, and decreases when the Vgs voltage becomes more positive.
- The characteristic of a p-channel JFET is controlled by the gate-source voltage.
- Fig. 9.47 shows the drain characteristics of a p-channel JFET.
Explore the similarities and differences between the construction of a p-channel IPIT and an n-channel JFET. Learn how the materials are reversed and how this affects the operation of the transistors.
