Abstract
A system (100) for calibrating data converters (101) includes a data converter (101) that receives an input signal and generates one or more pre-digital error correction codes from the input signal. A calibrator (150) receives the pre-digital error correction codes, formulating one or more transition voltage expressions using the pre-digital error correction codes, and compares the transition voltage expressions to one or more measured transition voltage values to generate one or more calibrated values. More specifically, the data converter (101) may be a pipelined analog-to-digital converter (101).
