Together with Prof. J.H. Huijsing he wrote the book “Frequency Compensation Techniques for Low-Power Amplifiers”, which was published by Kluwer Academic Publishers, Boston.


Nico van Rijn

Nico van Rijn joined the Philips Semiconductors automotive group in Sunnyvale, CA after receiving his MSc in Electrical Engineering from the Delft University of Technology in 1995, In 1998 he became part of the Amplifiers product line of National Semiconductor in Santa Clara and co-founded NSC’s Delft design center in the Netherlands focusing on low voltage low power amplifiers and audio products. In 2007 he started the Maxim Integrated design center in Delft for high precision signal chain products where worked through 2015. From 2015 to 2018 he was with Mellanox technologies focusing on multi-gigabit optical interconnect IC’s. Currently he is with Delft Semiconductor which he co-founded.


Henk de Graaf

Henk de Graaf received his Electrical Engineering degree (MSc) at the Electronic Instrumentation department of the TU Delft. In 2000 he joined National Semiconductor as a graduate student and held a Co-Op position as an analog design engineer in Santa Clara, CA. Later he joined National Semiconductor’s design center in Delft. From 2008 through 2015, Henk worked as an analog design engineer for Maxim Integrated in Delft. Over the years he was responsible for the development of more than twenty products. In 2015 Henk joined Mellanox Technologies where he designed on-chip supervisory and power management functions. Henk co-founded Delft Semiconductor in 2018.


Peter van der Hout

Peter van der Hout worked for over 10 years as a test department manager for TBP Electronics in Dirksland, The Netherlands. He became an application engineer with National Semiconductor’s Delft development center in 2003. From 2010 through 2015, Peter worked as a characterization engineer with Maxim Integrated in Delft. In 2015 Peter joined Mellanox Technologies where he worked as an characterization engineer. Peter co-founded Delft Semiconductor in 2018.


Chris Voerman

Chris Voerman received his Electrical Engineering degree (BSc) in Electrical Engineering from the Haagse Hogeschool in 1987. He started his career at Satcom, a company that developed and manufactured equipment for the consumer satellite market and telephones (normal, payphones, wireless) for the Dutch Telecom Provider (KPN). His role was to draw schematics, design the PCBs and assemble and test the prototypes. This company was taken over by CPS Europe, a member of the PijnenBurg Group in Vught.

In 2004 he changed from PCB Layout engineer to become a Layout Engineer at National Semiconductor. From 2008 through 2015 he was a Senior Layout Engineer with Maxim Integrated followed by Senior Layout Engineer with Mellanox Technologies. In 2017 he left the company to become a freelance Senior Layout Engineer (Dialog Semiconductor) and in 2018 he re-joined with his old team members to do the layouts for Delft Semiconductor.
