File:JFET MPF102 DataSheet.pdf

Parameter Value
[math]\displaystyle{ I_{DSS} }[/math]
[math]\displaystyle{ V_{GS(off)} }[/math]
[math]\displaystyle{ P_{max} }[/math]
[math]\displaystyle{ R_G }[/math] 3.3 M[math]\displaystyle{ \Omega }[/math]
[math]\displaystyle{ y_{fs} }[/math]
[math]\displaystyle{ y_{is} }[/math]
[math]\displaystyle{ y_{os} }[/math]
  1. Construct the JFET circuit below.
  2. Look up the [math]\displaystyle{ y }[/math] parameters of your JFET.
  3. Plot measurements of [math]\displaystyle{ I_D }[/math] -vs- [math]\displaystyle{ V_{DS} }[/math] by varying [math]\displaystyle{ V_{dd} }[/math] for [math]\displaystyle{ \left | V_{GS}\right | }[/math] = 0, 0.5, 1.0, 1.5 V. (40 pnts)
  4. Plot[math]\displaystyle{ I_D }[/math] -vs- [math]\displaystyle{ V_{GS} }[/math] (30 pnts)
  5. Calculate [math]\displaystyle{ y_{fs} }[/math] for your JFET (20 pnts)

Question

  1. Does [math]\displaystyle{ y_{fs} }[/math] depend on[math]\displaystyle{ I_D }[/math]? (10 pnts)
