Abstract: A method and system enables ADCs to be calibrated from reference signals wit h unknown parameters. A given analog reference signal (s(t)) is suplied to an ADC (310). The output (x(k)) of the ADC (310) is used by calibration logic (320) to estimate at least one parameter of the reference signal (s(t)). A F IR filter (455) accepts as input the x(k) signals and outputs an estimate (ŝ(k)) as the sampled instances of the s(t) signal. A reconstructi on table (So,...,SM-1) is created that approximates the analog input signal in the digital domain using the knowledge of the analog input signal waveform type. The actual ADC outputs (x(k)) are compared to the values in the reconstruction table (So,...,SM-1) to produce a correction table (350) for calibration. A continuous time reference signal may be utilized for training  the correction table (350). The method and system is data adaptive, so it ma y be applied, for example, with any sinusoidal reference input.
