摘要：
This paper describes a new multi-level switching amplifier concept, targeting increased power efficiency for analog signals with a very high crest factor. Interesting application fields include audio power amplifiers or line drivers in central-office ADSL and VDSL equipment. Calculations prove its superior power efficiency compared to conventional class-D switching amplifiers as well as linear class-AB and class-G amplifiers. A silicon implementation of a multi-level switching VDSL line driver chip is currently in progress.
