Determination of Nonlinearity and Effective Resolution of an A / D Converter for Arbitrary

component in video, radar, communications, high-speed data acquisition and measurement systems. ADC decides the overall accuracy of such systems. Many times the input to ADC in an application is different than standard signals such as sine wave or triangular wave. As ADC parameters are dependent on input frequency and other test conditions so parameters determined using standard signals are not useful. Therefore dynamic testing of ADC under application conditions is needed. This paper discuses methodology to test ADC using application input. of Bits (ENOB) of 5 bit simulated ADC is determined based upon INL computation. It is expected that this work will initiate research towards ADC testing using application input.
