books on amplifier concept/design

[maldecido33 10+ year member]

looking to mess around some with building/designing small (a couple watt) amplifiers; all classes, as well as some using the tripath chipset.

i have access to any component/technology i'd need here at campus

i'm pretty unfamiliar with literature on the subject, just looking to get a feel for what's out there.

thanks alot

dont know any books off the top of my head, but if you are on campus your library should have some good books.

douglas self has some books. i think there are a few others out there. diyaudio.com has a forum for this as well.

my advice is to start with the high level chip amplifiers, then work toward the lower level design.

sound.westhost.com also has some suggestions.

the majority of linear amplifiers have a simple design:

1.) differential pair

2.) voltage amplification stage

3.) current amplification (aka output) stage.

and sometimes these are broken down further.

class D amps typically have:

1.) PWM/comparator

2.) Output stage

3.) Filter

and this can be expanded on as well.

both linear and swtiching amplifiers make use of feedback to aid in linearity. chipamps are nice because the amplifier is more of a blackbox, and the component choices are done for the high-level design.
