The SOPA xDSL Line Driver
SINCE the high voltage line drivers presented in this book are based on the self-oscillating class D principle, the behavior model of the SOPA [Pie04] is refurbished in this chapter. This model provides fast architectural explorations for the designer of highly efficient power amplifiers based on the self-oscillating principle. For a mass product, like xDSL, in a dynamic market, time-to-market is a crucial parameter. Therefore, fast architectural exploration is very important, especially when technology migrates from one node to another.
