Abstract: Data converters play a vital role in converting analog signal information to its equivalent digital information. In general purpose computing devices, industrial electronic equipment, and biomedical equipment especially in display device modules, they make use of these converters for displaying accurate results very effectively with high precision. these data Converters establish a key rolein between the analog transducers sensors, actuators to digital signal processing and helps for easy data processing in systems, like wireless communication systems and also in multi-channel biomedical devices etc.,There are variety of converters are available for different applications at different levels considering their parameters such as speed of conversion resolution, gain accuracy, etc., and In this paper, a comprehensive overview of the errors and the different calibration are discussed. The research work will give the different concepts and techniques for error calibration of ADC for an effective output with low INL and DNL obtaining high ENOB.

Keywords: ADC, Calibration, Errors, INL, DNL, ENOB.
