Figure PD.6(a) shows the circuit symbol of a device known as the p-channel junction
Chapter 0, Problem D.6(choose chapter or problem)
Figure PD.6(a) shows the circuit symbol of a device known as the p-channel junction field-effect transistor (JFET). As indicated, the JFET has three terminals. When the gate terminal G is connected to the source terminal S, the two-terminal device shown in Fig. PD.6(b) is obtained. Its iv characteristic is given by i = IDSS 2 v VP v VP 2 for v VP i = IDSS for v VP where IDSS and VP are positive constants for the particular JFET. Now consider the circuit shown in Fig. PD.6(c) and let VP = 2 V and IDSS = 2 mA. For V + = 10 V show that the JFET is operating in the constant-current mode and find the voltage across it. What is the minimum value of V + for which this mode of operation is maintained? For V + = 2 V find the values of I and V. Figure PD.6
