Tittle:
Input bandwidth adjustment system for time-interleaved analog-to-digital converters
Summary:
Researchers from a Spanish university specialized in the design and test of integrated circuits, have developed an input bandwidth adjustment system capable of correcting bandwidth-mismatch-related errors with a much simpler implementation than conventional digital correction systems. Companies focused on the design and implementation of analog and mixed-signal integrated circuits interested in a license agreement are being sought.
Description:
Manufacturing process variations alter the electrical characteristics of any integrated circuit. Because of that, new systems tolerant to these variations are topics of active research. Specifically, those focused on time-interleaved analog-to-digital converters (TI ADCs), where bandwidth mismatch between parallel input sampling switches reduces their maximum attainable linearity.

Spanish researchers specialized in the design and test of integrated circuits, the use of electronic instrumentation and robot control, have developed a new analog input bandwidth adjustment system that can be used to equalize the input bandwidth of each parallel input sampling switch of TI ADCs.

The proposed calibration system for TI ADCs could be interesting for companies in the electronic sector, and specially for those focused on the design and implementation of analog and mixed-signal integrated circuits willing to commercially develop this system through a license agreement.

Advantages and Innovations:
The proposed analog adjustment system together with existent digital detection techniques make up a cutting edge mixed-signal calibration system, as an alternative to conventional all-digital calibration ones. Such system fully exploits the robustness of a digital detection and the simplicity of the proposed analog correction hardware.

So, the analog input bandwidth adjustment is ready to replace conventional adaptive digital calibration filters commonly used to correct bandwidth-mismatch-related errors.

The proposed analog correction system offers a much simpler implementation than conventional digital correction systems, that is, less die area and power consumption requirements. This makes TI ADCs suitable to low die area and power consumption constraints.
