Sine wave-based histogram techniques are based on histogram techniques which are important method of research for characterization of analog-to-digital converter. To find out signal-to-noise ratio (SNR) via ADC is point of interest for young researchers. Proposed work estimates signal-to-noise ration using histogram test. Through simulation with software ENOB of ADC is studied and analyzed for SNR calculation. As effective number of bits get increases, noise get decreases.
