Keywords:Xignal? National? continuous-time sigma delta ADC? ADCs?

Boosting its position in the data conversion market, National Semiconductor Corp. has acquired Xignal Technologies AG. The Germany-based company is a pioneer in the development of continuous-time sigma delta architecture that enables high-resolution (12bits and above) ADCs at megahertz speeds with reduced power levels compared to traditional pipeline solutions.

Under the transaction, National acquires Xignal's technology and design team. This investment in continuous-time sigma delta intellectual property (IP) augments National's existing sigma delta IP and complements its ongoing sigma delta technology development.

Initial products from the acquisition will target applications requiring a high level of signal path integration and extremely low power, such as medical ultrasound imaging, and will expand over time to address test and measurement as well as communication apps.
