The measurement of static test parameters for an analog-todigital converter (ADC) requires a large volume of test data, especially for a high-resolution ADC. This paper proposes a reduced-code test method for pipelined ADCs that does not compromise test accuracy. The proposed method calculates fault information at each stage by using sub-histograms. The simulation results based on 12-bit pipelined ADCs show a maximum integral nonlinearity error of 0.590 LSB with only 3.92% of the codes required for the conventional histogram-based method.
