Klaas Bult



Klaas Bult’s innovations regarding analog and mixed-signal integrated circuit design have enabled systems-on-chip technologies that have had great societal and economic impact. During the 1990s when there was skepticism whether sensitive analog circuits could be integrated on the same die as larger digital components, Bult saw that cointegration was an economic necessity and demonstrated how it could be achieved. The analog-to-digital and digital-to-analog chips he developed while working for Broadcom enabled single-chip, high-performance communication systems widely used for data transfer in set-top boxes, cable modems, Ethernet, and automotive applications. His work was key to Broad-com growing from a small startup to a world leader in broadband semiconductors. Today, it is practically impossible to transfer data over the Internet without utilizing Bult’s circuits techniques.

An IEEE Fellow, Bult is a professor with Delft University of Technology, Delft, Zuid Holland, the Netherlands.
