ABSTRACT
Data converters, or specifically analog-to-digital converters (ADC) and digital-to-analog converters (DAC), play an important role in the design of data acquisition units in communication and microprocessor-based instrumentation systems. They include analog and digital building blocks and form the main interface component in mixed-signal processing systems. The choice of a number representation system has repercussions on the complexity of algorithm implementations for arithmetic operations and the input or output interface of the data converter with other circuits. Data converters are generally designed to meet the requirements of various applications such as imaging, video, instrumentation, control, and communication systems. Data converters used in portable equipment should meet the requirement of low supply voltage and low power consumption. One feature of data converters such as DAC and ADC is that either the input or output is in digital form and can be represented using binary codes.
