Abstract
An algorithm to compensate for the effect of signal-source distortion in the measurement of the dynamic performance of analog-to-digital converters (ADCs) is described. The algorithm uses two sets of measurements: one set taken with the function generator and another taken with an all-pass filter inserted between the function generator and the ADC. Simulation results indicate that ADCs with a dynamic range of 60-70 dB can be measured with an absolute accuracy of better than 0.2 dB using a signal generator that has -40 dB distortion components
