Gabriele Manganaro, Gil Engel: Randomized quad switching. ANALOG DEVICES, Patent Capital Group, February 28, 2017: US09584151

Reducing distortions in a digital-to-analog converter is a challenge for circuit designers. For current steering digital-to-analog converters (DACs), a quad switching scheme has been used to remove code-dependent glitching which is otherwise present in dual switching schemes. However, due to various ...

Ahmed Mohamed Abdelatty Ali, Paritosh Bhoraskar, Huseyin Dinc, Andrew Stacy Morgan: Background estimation of comparator offset of an analog-to-digital converter. ANALOG DEVICES, Patent Capital Group, March 21, 2017: US09602121

A pipeline analog-to-digital converter (ADC) converts an analog input signal over several stages, where a stage generates a residue for the subsequent stage to digitize. The residue is generated by coarsely quantizing the analog input signal to generate a digital code, which is used to reconstruct t ...

Richard E Schreier, Alexander Newcombe, Ross Willett, Andre Straker: Remote evaluation tool. ANALOG DEVICES GLOBAL, Patent Capital Group, August 15, 2017: US09733306

Remote evaluation, e.g., web-based evaluation, lowers the evaluation barrier by allowing an engineer to gain experience with an integrated circuit (IC) using a client (e.g. a web browser) on a remote computer (e.g., a machine remote from the IC being evaluated but local to the engineer) to activate ...

Eric Otte: Measuring and correcting non-idealities of a system. ANALOG DEVICES, Patent Capital Group, April 17, 2018: US09945901

Many systems implement calibration schemes to measure and correct for the non-idealities. Such systems can be complex, which makes them impractical to implement since the cost can potentially outweigh the benefits of the calibration scheme. To implement efficient and effective calibration, non-ideal ...
