Delta sigma A D converters : practical design for communication systems The emphasis of this book is on practical design aspects for broadband analog to digital converters for communications. The embedded designs are employed for transceivers in the field of Asymmetric Digital Subscriber Line (ADSL) solutions and Wireless Local Area Network (WLAN) applications. An area and power efficient realization of a converter is mandatory to remain competitive in the market. The right choice for the converter topology and architecture needs to be done very carefully to result in an attractive figure of merit (FOM). The book begins with a brief overview of basic concepts about ADSL and WLAN to understand the requirements on Analog to Digital (A D) converters.
