Towards advanced audio power amplifiers

In his Guest Editorial, David Zan argues that almost all power amplifier designs have gyrated to a few standard design topologies. However, he believes that significant improvements are possible with what he calls advanced designs, which focus on advanced compensation methods beyond the ubiquitous Miller-dominant pole compensation. In this article he gives a brief overview of the topologies he is considering, and he will be back in a future article with detailed designs and solutions.
