I was talking to a friend last week about being an author and remembered that I wrote a few articles "back in the day".  He suggested putting links to them on here....

Here's one about a Class-D subwoofer amp (2001):

(download to view if the link stalls)
"Powering the modulator circuits and FET drivers reduces efficiency."

Here's one about amp Class designations (2004):

"Many fictitious class designations have been conjured up by switching amplifier manufacturers, such as Class-T, Class-J, Class-X, etc, but they are still simply variations of Class-D amplifiers."

Here's one comparing Class-G to Class-H (2004):

"The power supply rails in a moving rail amplifier can also cross zero in some implementations...."

Here's one about "amp spec games" (2004):
http://www.livesoundint.com/archives/2004/dec/power.pdf
"DNR is mostly used to measure digital devices, such as A/D (analog to digital) and D/A converters, and has recently become prevalent in the
measurement of digital input amplifiers."

Happy reading!  Thanks.
