The JFET (Junction Field Effect Transistor n-channel)

File:JFET MPF102 DataSheet.pdf

1.) Complete the table below for the JFET.

Characteristic	Symbol
$I_{DSS}$
$V_{GS(off)}$
$P_{max}$
$R_G$	3.3 M$\Omega$
$R_D$
$y_{fs}$
$y_{is}$
$y_{os}$

2.)Construct the JFET circuit below.

3.)Plot measurements of $I_D$ -vs- $V_{DS}$ by varying $V_{dd}$ for $\left | V_{GS}\right |$ = 0, 0.5, 1.0, 1.5 V. (40 pnts)

4.)Plot$I_D$ -vs- $V_{GS}$ (30 pnts)

5.)Calculate $y_{fs}$ for your JFET (20 pnts)

Question

1. Does $y_{fs}$ depend on$I_D$? (10 pnts)
