re: A new audio amplifier topology with push-pull transimpedance stage - Part 2: Biasing, stability and AC performance

I have always worked to get rid of all the power supply noise so that the high level of power supply noise rejection that was required was not so great. In addition, the tolerance of components needed to filter out power supply noise are far less critical than those needed for good amplifier PSRR design. Probably a combination of the two methods would be the best choice. Of course, optimizing for the minimum cost was never the highest priority for our group, nor for our customers. Somebody else can always make something cheaper and not quite as good.

Hi, sorry for my english. About the power supply rejection, in this old Luxman: http://www.eserviceinfo.com/download.php?fileid=48149 can be see the use of differents supplies for each stage of the power amp in a cheap and good way, the effect in the sound quality are very good.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
