"If a varicap diode is part of a resonant circuit as in Figure above, the frequency my be varied with a control voltage, Vcontrol."

Is it to be may instead of my?

"Another PIN diode application is a the antenna switch here for a direction finder receiver."

Here something seems to be wrong as well.

"Diodes based on organic chemicals have been produce using low temperature processes."

Sorry, I am far from being an expert in E grammar, but should it be have been produced?

You are correct sir.

Polymer diode

Diodes based on organic chemicals have been produce using low temperature processes. Hole rich and electron rich conductive polymers may be ink jet printed in layers. Most of the research and development is of the organic LED (OLED). However, development of inex

"The approximage voltage gain of the C-E amplifier in Figure belowb is -RL/REE."

Approximate? Below?

 

The sentence might read better as: "The approximate gain of the C-E amplifier in the figure below is -RL/REE."

The b is probably a leftover from a reference to a Figure b in an earlier version.

 

If Dennis ever responds to this thread we probably ought to close this one and start a new one. Has anyone emailed or PMed him? Lots of good corrections here.

 

I wish I knew who Dennis was... I haven't emailed.

 

Not to be concerned. Dennis Crunkilton is the Ebook editor. He looks in to this forum now and again to find corrections to apply to it.

"This restores the AC gain since the resistor is a short for AC signals."

Isn't a capacitor a short for ac signals?

I will drop him an e-mail. Some of these may have been silently updated, in which case they will pop onto AAC shortly.

I did notice a correction the other day at: http://www.allaboutcircuits.com/vol_2/chpt_6/6.html

In paragraph 2:

This formula is applicable to series resonant circuits, and also parallel resonant ciruits if the resistance is in series with the inductor.

Spelling correction, should obviously be "circuits",

" Iis it possibe to avoid thermal runaway without having to suppress the amplifier's inherently high voltage gain?"

Iis seems to be a typo.

 

Having finally found that sentence, it appears that "Is it possible to avoid....." would be the correct spelling.

" The the semiconductor die in the TO-220 and TO-247 plastic packages is mounted to a heat conductive metal slug which transfers heat from the back of the package to a metal heatsink, not shown"

Two "the"s in a row.

 

the same place:

"electrically isolate the these from a grounded heatsink by an interposed mica or polymer washer. "

something seems to be wrong here.

"This distortion distortion is unacceptable in many applications like high-fidelity audio."

the word distortion is repeated twice.

 

Guyz, sorry for the off-top, but might you please advise me when the chapters on MOSFET and JFET are ready?
