About Me

Anne-Johan Annema

Anne-Johan Annema received the MSc. and PhD degrees in electrical engineering from the University of Twente, Enschede, The Netherlands, in 1990 and 1994, respectively. His doctoral work was on the subject of mathematical analyses and electronic implementations of analog neural networks. It was published as a book: Feed-Forward Neural Networks (Boston, MA: Kluwer, 1995).

In 1995, he joined the Semiconductor Device Architecture Department of Philips Research in Eindhoven, The Netherlands, where he worked on a number of physics-electronics-related projects. In 1997, he joined the Mixed-Signal Circuits and Systems Department at Philips NatLab, where he worked on a number of electronics-physics-related projects ranging from low-power low-voltage circuits, fundamental limits on analog circuits in cojunction with process technologies, high-voltage in baseline CMOS to feasibility research of future CMOS processes for analog circuits.

His current research interest is in physics, analog and mixed-signal electronics, and deep-submicrometer technologies and their joint feasibility aspects. This spans research from switched mode RF power amplifiers, references, optical functionality on CMOS and other circuits and systems combining physics, mathematics and electronics. Since June 1 2000 he is with the IC-Design group in the department of Electrical Engineering at the University of Twente, Enschede, The Netherlands. He is also part-time consultant in industry and in 2001 he co-founded ChipDesignWorks. Anne-Johan holds 11 patents in circuit design and is the recipient of the 2003 and 2006 Opel (educational award EE) and of the 2012 educational award AT. From 2017 to 2020 he was program director Electrical Engineering.
