Cmos Integrated Analog-To-Digital And Digital-To-Analog Converters

Аннотация

In this introduction an overview of the contents of this book will be given. Analog-to-digital (A/D) and digital-to-analog (D/А) converters provide the link between the analog world of transducers and the digital world of signal processing, computing, and other digital data collection or data processing systems. Numerous types of converters have been designed that use the best technology available at the time a design is made. High-performance submicron CMOS technologies result in high-resolution or high-speed A/D and D/А converters that can be applied in digital audio, digital video, instrumentation and signal processing systems. Furthermore, sub-micron CMOS technologies show an increase in conversion speed into the Giga Hertz range. Applications in these areas are, for example, in high-definition digital television, digital receiver applications, Local Area Networks, cable modem chips and digital oscilloscopes. The availability of high-speed memory chips results in so-called “one-shot” memory applications in these oscilloscopes. In this book different techniques to improve the accuracy in high-resolution A/D and D/А converters will be discussed. Also, special techniques to reduce the number of elements in high-speed A/D converters by a repetitive use of comparators will be described.
