Consider a JFET that has the curves shown in Figure 9.34 Estimate the value of the threshold voltage V_T. Justify your answer. For what value of the gate-source voltage is the current 2.2 mA? For what values of the drain-source voltage is the current 2.2 mA? What current flows through the circuit saturation) region? circuit of Figure 9.35 when it is in the flat (FET If the FET is in the circuit of Figure 9.35, for what values of the drain-source Voltage is the FFT in the Hat region? Justify.

Solution

vt = 1v is preferable and in generalised conditon taken for prope apllication

for the vgs = -0.2, -0.5,-0.9 the id= 2.2ma
