Review the data sheets for the MPF102 JFET and answer the following: Determine the maximum drain-source voltage V_DS for the MPF102 JFET. Determine the maximum I_DSS and V_P or V_GS(off) for the MPF102 JFET. Determine the power rating P_D(max) for the MPFI02 JFET. Determine the MPFI02 input capacitance Cm and reverse transfer capacitance C_rss. Determine the operating point Q for the circuit of Figure 10(b).

Solution

Vdd=16v

Id=Vdd/(Rd+Rs)

Id=16/(1.5k+510)=7.96mA (from circuit b)

(1A)::

:from circuit a:

-Vdd+Id(Rd)+Vds=0;

Vds=Vdd-Id(Rd)

Vds=16-7.96m(1k)

Vds=8.04v

Qno:2)=

when Vgs=0;

Idss=Id=7.96mA

Vds=Vgs-Vp

Vds=-Vp since Vgs=cutoff=\'0\'

i.e, Vp=-8.04v

Qno=3 ans:

Pd(max)=Id^2(Rd)

=(7.96m)^2(1k)

=126.67mW
