EMRFD Chapter 2 Errata.
  (15 Jan 10)

p2.2, Fig 2.3.    The diode in the figure has the battery polarity wrong.   The correct figure is shown below. (27Sept09) 


p2.5, right col, 0.8 inch down from text top.   Replace JET with JFET.  (15 Jan 10)    

p2.6, JFET analysis, General comments:   The equations that describe JFET current contain the term Vsg.   This is the source voltage with respect to the gate, or Vs-Vg.       Fig 2.19 includes an equation that is called the "Basic FET equation."   This has a positive sign within the bracket.   If the equation had been written in terms of Vgs (gate voltage with respect to the source) there would be a negative sign.   The key points to keep in mind are that Vp is negative (for an N channel depletion mode JFET) and that Vgs=-Vsg.    Here's a summary of useful JFET equations.  This is clarification info.  It is not an errata.

p2.31, Top of middle col.   Replace "have Q" with "have low Q".    (29Aug9)  

p2.36, Fig 2.97 Caption.   Change the units for L1, L2, and L3 from mH to uH.    (While L1 and L2 are correct in the Third Printing, L3 is still shown as 15 mH.   It should be 15 microhenry.   (17April9)
   (12July03)  

  p2.37, right column, 3.7 inches down from text top:   replace "thermal communications" with "thermal contact"   (9Dec03)

  p2.37, right col, 3.8 inches down from text top:  Replace "Some designs us a ...." with "Some designs use a ....." (17April09) 

p2.39, right column, 0.9 inches up from text bottom:  replace "network the Beginner's" with "network for the Beginner's"  (9Dec03)

p2.41, right column, 1.2 inches up from text bottom:  replace "This loss of no" with  "This loss is of no"   (9Dec03)
