Integrated circuit design (I),ystems) pushes the clock frequency up to 1.024MHz. In audio band (20kHz), a 10.2MHz clock rate would be needed, while for video, up to 5MHz, 2.56GHz! Apart from the necessary increase in power consumption, increasing the clock frequency generates additional problems such as jitter, switching noise, etc.

Integrated circuit design (II),ane is perfectly linear. The drawback of such gross conversion, which on the other hand provides very robust operation, is the large quantization noise, whose effect can be attenuated only by increasing the oversampling ratio.

Book 1999nlike 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 pro- cessing - a desirable feature regarding the implementation of NO in
