摘要：

Two changes are recommended for procedures used in building two-dimensional state-space error correction tables to compensate high speed analog-to-digital converters (ADC's). The modifications require three frequencies to calibrate all states as well as extrapolation of estimated outputs to achieve a straight line input-output integral characteristic for the ADC. A simulated 6-bit ADC with only 35-dBc spurious free signal range is shown to be correctable to 53 dB over 80% of the Nyquist band when suggested changes are used to calibrate the ADC.
