DNL&INL
Although integral and differential nonlinearity may not be the most
important parameters for high-speed, high dynamic performance data
converters, they gain significance when it comes to high-resolution imaging
applications. The following application note serves as a refresher course
for their definitions and details two different, yet commonly used
techniques to measure INL and DNL in high-speed analog-to-digital
converters (ADCs).
Manufacturers have recently introduced high-performance analog-to-
digital converters (ADCs) that feature outstanding static and dynamic
performance. You might ask, "How do they measure this performance, and what
equipment is used?" The following discussion should shed some light on
techniques for testing two of the accuracy parameters important for AD
