It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractThe present invention is directed to a diagnostic compiler for use with a pipeline analog-to-digital converter (ADC) having code sequences corresponding to stages thereof. In one embodiment, the diagnostic compiler includes a transition locator configured to determine transition locations for the code sequences. The diagnostic compiler also includes a characteristics indicator coupled to the transition locator and configured to provide at least one characteristic of the ADC based on the transition locations.Other References
