Top-Down Design of High-Performance Sigma-Delta Modulators

The interest for :I:~ modulation—based NO converters has significantly increased in the last years. The reason for that is twofold. On the one hand, unlike other converters that need accurate building blocks to obtain high res­ olution, :I:~ converters show low sensitivity to the imperfections of their building blocks. This is achieved through extensive use of digital signal processing — a desirable feature regarding the implementation of NO interfaces in mainstream CMOS technologies which ...
