1.
Conduction of N-type electrons in in the conduction band.

2.
A realistic machine most often looses some of its input energy as heat in transforming it into the output energy stream.

3.
The cross-section in Figure ? above looks a bit more complex than a simple PN junction

4.
Maybe it's just me, but using the word save is confusing, why not just be clear and use the word "except"...
There is no current flow, save leakage current, in the collector circuit.

5.
This correspondes to 100% emitter current splitting between the base as 1% and the collector as 99%.

6.
Should this have been 0.7 V?
The heavy doping in the emitter gives the emitter-base a low approximate 7 V breakdown voltage in small signal transistors.

7.
The MOSFET described above in [the] Figure ? above is known as an enhancement mode MOSFET

Thanks for taking the time to give us some feedback.

1.

Yes there is a repeated word about half way down.

2.
A realistic machine most often looses some of its input energy as heat in transforming it into the output energy stream.
Unless I'm missing something, "looses" is the correct spelling.

EDIT: No I stand corrected, it should be "loses".

3.

Are you seeing a question mark? It says above and links to the above picture in this section of the text, i.e. http://www.allaboutcircuits.com/vol_3/chpt_2/7.html#03301.png

As far as I can see, this bit is correct.

4.

I agree, "save" is a bad word here and I agree with your suggestion of "except" or "except for".

5.
This correspondes to 100% emitter current splitting between the base as 1% and the collector as 99%.
Yes, the word should be "corresponds".

6.
Should this have been 0.7 V?
The heavy doping in the emitter gives the emitter-base a low approximate 7 V breakdown voltage in small signal transistors.
If I have read this correctly, this is a breakdown voltage in reverse-bias conditions, therefore is not necessarily 0.7V as would be the case for a forward-biased silicon PN-junction.

7.
The MOSFET described above in [the] Figure ? above is known as an enhancement mode MOSFET
This bits hould be: "The MOSFET described in the Figure above is known as an enhancement mode MOSFET." - the word above should link to the relevant figure as is currently the case, i.e. http://www.allaboutcircuits.com/vol_3/chpt_2/10.html#03423.png

Thanks.

I don't see a question mark. What I meant by that is the sentence should refer to a certain part of the figure, ie, figure a, b, c, or d.

Thanks for responding to feedback. This is a definite advantage over a textbook in that it usually has a bunch of errata, but never gets resolved. Oh wait, they just reprint the next edition and sell it for $120. #### Dave Joined Nov 17, 2003 6,969 I don't see a question mark. What I meant by that is the sentence should refer to a certain part of the figure, ie, figure a, b, c, or d. Thanks for the clarification, I now see your point. In both cases where you have outlined this issue, the reference to the figure has referenced the whole figure, therefore I am of the opinion that, since the figures are directly above the text in question, that using the link "above" is adequate. I will await Dennis' input on whether he thinks further clarity is required in this regard. Thanks for responding to feedback.

Not a problem, if people take the time to give us feedback and suggestions, the least we can do is give them a response. I agree, this e-book benefits from the many eyes that are cast over it.

Thanks.

It was supposed to refer to the (b) part of the figure. This change entered

Thanks for finding the errors.

Items 1 through 5 have been enetered at ibiblio.

#6 Emitter of a BJT is heavily doped like a zener diode. The reverse biased B-E junction is sometimes used in circuits in place of a low voltage zener diode-- about 7 V.

#7 Left this one the same. The HTLM version of the volumes is a little confusing with respect to figures. The PDF version has real figure numbers. The HTML version links to the proper figure with one of the following words to give a hint as to where it is: above, below, previous. Figure above (in HTML) sounds a little strange as compared to the Figure 2.39 (or whatever) in the PDF version, but it gets the job done.
