Abstract
An analog-to-digital converter (ADC) is used for dynamic tracking nonlinearity correction. The correction employs an analog sampling technique to determine the signal derivative by measuring the derivative current arising from sampling an analog input signal undergoing analog-to-digital conversion, at the sampling instant. The analog derivative sampling technique achieves significant reduction in power consumption with less complexity compared with a digital approach, with strong improvements in HD, SDFR, and IMmeasures.
